Who it suits
Is it right for you?
Great for
- Dry-fly anglers carrying a varied selection. There's room to organise different sizes and styles rather than cramming everything into one mixed box.
- Anglers with larger dries and hoppers. The deeper format accommodates bulkier patterns that aren't a natural match for slimline storage.
Maybe skip if
- Minimalist anglers carrying only a few flies. A smaller box may make better use of limited vest or chest-pack space.
- Anyone needing confirmed waterproof storage. A magnetic closure alone doesn't establish a watertight seal; don't choose this on that assumption.

Quick verdict
A sensible home for bushier flies
The Fulling Mill Dry Fly/Hopper Box makes sense if you carry a decent selection of dries and want something deeper than a slimline fly wallet. Slit foam, a magnetic closure and a frosted lid keep the basics refreshingly straightforward.
Treat the 216-fly capacity as a storage ceiling, not a target for chunky hoppers. Give those bigger dressings some space and you've got a useful specialist box; carry just a handful of dries and it could be more box than you need.

The impact-resistant polycarbonate shell and grip-enhancing ridges are sensible choices for protecting and handling delicate flies.
Useful depth and slit-foam storage suit dry flies well, provided bulky dressings aren't crowded together.
Organised, accessible flies can help your preparation, but a storage box has only an indirect effect on catches.
The viewing lid, magnetic closure and pre-cut slits keep everyday fly selection straightforward.
Its specialist features offer the most useful return to regular dry-fly anglers who genuinely need the extra room.

The full rundown
Everything you'll want to know about the Fulling Mill Dry Fly Box
Dry flies can be awkward little things to store. The hook takes up hardly any room, then the hackle, wing and legs spread out like they own the place. Squeeze them into a shallow box and suddenly that tidy selection isn't looking quite so tidy. The Fulling Mill Dry Fly Box tackles that particular faff with a deeper format aimed at dries and hoppers. It's a specialist bit of storage rather than a reason to replace every fly box you already own.
First, let's get the name straight. This is Fulling Mill's Dry Fly/Hopper Box, product code 1825. It measures 32 × 106 × 186 mm and has a stated capacity of 216 flies. That's a substantial selection for a day on the river or a reservoir session with surface-feeding fish in mind. The capacity gives you plenty of scope to split patterns by style and size, though it doesn't mean you should cram a huge, leggy hopper into every available position.
The depth is the bit to pay attention to. A slim box is cracking for keeping bulk down, but it isn't always kind to a bushy dressing. Here, the format accommodates a variety of fly sizes, including larger patterns. That's useful if your dry-fly selection runs from modest river flies to more substantial offerings. Just remember that overall box depth isn't the same thing as guaranteed clearance for absolutely every fly. Particularly tall wings and sprawling legs still need a sensible bit of space.
Inside, a foam insert with pre-cut slits holds the flies. That gives you an obvious place for each hook and makes a planned layout easy enough to maintain. You might keep smaller dries together, put hoppers in their own area and leave spare positions alongside the bulkiest dressings. Dead handy when a fish starts rising and you want the right fly without shuffling through a jumble. Seat hooks carefully in the slits rather than repeatedly stabbing fresh holes into the foam.
The frosted lid is another useful touch. You can view the contents without opening the box, so finding the right selection in your bag doesn't have to involve opening every lid. Don't expect it to replace a close look when you're choosing between near-identical flies, mind. Fine differences in size, colour or dressing are still easier to judge with the box open. For a quick check that you've grabbed the dries rather than something else, though, it's a sensible feature.
Around that sits an impact-resistant polycarbonate outer shell, with guide ridges intended to improve grip. That's a practical combination for something you'll handle beside the water, often while keeping one eye on a rising fish. The magnetic closure also keeps the fastening arrangement straightforward. None of that makes the box indestructible or proves it'll keep water out if you take a dunking. Treat it as protective storage for delicate flies, not a sealed safe you can happily leave bobbing about in the margins.
In session terms, this suits an angler who likes a proper selection ready to go. On a river, arrange it so likely first choices are easy to spot, with alternatives nearby rather than scattered across the insert. On stillwaters, give larger hoppers and other bulky dries their own breathing room. The aim isn't to win a competition for the most flies carried. It's to make changing patterns calmer and quicker when fish are showing, especially when you've only got a short spell of useful surface activity.
The buying decision comes down to whether your current storage is actually getting in the way. If you're squeezing bushy flies under a lid or tangling neighbouring dressings whenever you pick one out, this is a sensible format to consider. If you only carry a dozen small dries, its size and capacity may be overkill. Measure your intended pocket before buying, don't count on using every slot for big patterns, and let damp flies dry before closing them away. Simple habits, but they help keep a useful box working as it should.

Our take
Room for the dressing, not just the hook
A fly fitting into a slit doesn't mean its hackle, wing and legs have enough room. This box's useful selling point is its depth, especially when your selection includes larger dry flies and hoppers.
The trick is to organise for access rather than maximum numbers. Leaving gaps around bulky patterns makes choosing a fly less fiddly and helps avoid neighbouring dressings getting tangled.
The box itself
Closer look: useful depth and straightforward storage
You're buying an empty, dedicated dry-fly and hopper box with a polycarbonate shell and slit-foam insert. The appeal is the combination: useful depth for larger dressings, individual holding positions and a lid that lets you see the contents. Nothing complicated, just features that fit the job.
The magnetic closure avoids a separate clip-style fastening, while the outer ridges give your fingers a more defined surface to hold. At 186 mm long, this is a box to check against your vest or pack rather than assuming it'll disappear into any pocket.
Worth knowing. The 216-fly figure isn't a promise that 216 bulky dressings will sit comfortably together. Space flies according to their wings, hackles and legs, not just where an empty slit happens to be.
Your fishing
Who it suits: dry-fly regulars with more than a token selection
If dry-fly fishing is a regular part of your season, a dedicated box makes good sense. You can build a clear layout around your waters and keep bushier patterns separate from tightly packed subsurface flies. That organisation is especially useful when changing size or profile to suit what's happening in front of you.
It's less compelling for the travelling-light angler who only carries a few dries as backup. Capacity you don't use still takes up pocket space. Equally, anyone choosing storage specifically for a watertight seal needs to check that requirement separately rather than reading it into the magnetic closure.
Quick answers
FAQs in full: identity, capacity and keeping flies dry
Is this the Dry Fly/Hopper Box? Yes: Fulling Mill's product code is 1825, and the dimensions are 32 × 106 × 186 mm. That's the model covered here, rather than another box from the wider Fulling Mill range.
Can you fill it with 216 large hoppers? Don't plan around that. The stated capacity is 216 flies, but dressing bulk determines comfortable spacing. Leaving a position empty beside a broad or leggy pattern can make it much easier to remove without snagging its neighbour.
Is it waterproof, and does it come loaded? Flies aren't included, and the magnetic fastening isn't itself proof of waterproofing. If flies go back damp during a session, open the box somewhere safe afterwards and allow them to dry before longer-term storage. That's good housekeeping for hooks and dressings alike.

02Will it hold 216 large hoppers?
Will it hold 216 large hoppers?
The stated capacity is 216 flies, but large hoppers need more space around their dressings. Leave gaps where necessary rather than expecting every position to suit a bulky fly.
03Is it waterproof, and are flies included?
Is it waterproof, and are flies included?
Flies aren't included. It has a magnetic closure, but that shouldn't be taken as a waterproof guarantee. Keep it out of the water and let damp flies dry before storing them closed up.
