Rows of tiny nymphs and dry flies docked in The Eddy's magnetic insert

Size 24?No problem.

When the fishing pressure is on, use small flies.

Why? It's Fly Fishing 101. Small flies — especially microscopic size 24s — look like what fish are actually eating.

They're also a pain to shove into silicone or foam. Flat magnets make them hard to pull off, and the flies become a tangled mess.

The Eddy was built to make small flies easy to store. It works just as well for any fly in your box.

Patent-pending fly retention

Four ways to dock a fly.

Rare-earth magnets and an engineered polymer insert work together. Pockets and channels guide each fly into position, magnets hold it there — even upside down or thrown around in the back of your vehicle.

Hooks Up: a small beadhead nymph held bead-down in a circular magnetic pocket Hooks Down: a big beadhead nymph pulled snug into the channel, eye facing out Standard: a mayfly dry fly resting along a magnetic channel Loading Zone: a fly's eye set in the small center slot with tippet fed through

For size 16 and smaller nymphs

Hooks Up.

Magnets pull the bead into the circular pocket. Tiny nymph, docked. No forcing it into silicone.

Foam vs. The Eddy

Foam had a good run.

The Eddy's empty insert: engineered polymer channels and pockets with no foam or silicone
The insert. Engineered polymer over hidden rare-earth magnets. Nothing to compress, tear, or wear out.
Foam, silicone & flat magnets The Eddy
Tiny flies A pain to shove into foam or silicone. Hard to pull off flat magnets. Pockets guide each fly in. Magnets hold it there.
Hooks & barbs Get stuck in foam. Snaggy. No careful placing. Nothing to snag.
Organization Flat magnets turn flies into a tangled mess. Tangle free. Organized and protected.
Over time Foam rips. Slots compress and wear out. Nothing to compress, tear, or wear out.

Testers said it first.

“Love that I don't have to be super careful putting a fly away and that hooks/barbs aren't getting stuck in foam.”

Early tester

“I like how much easier it is to grab and place smaller flies, rather than trying to place hook bends into small foam slots with itty bitty flies.”

Early tester

“I hate how snaggy foam boxes get, love the diversity of flies this can hold comfortably.”

Early tester

“@westfork.fish has your new favorite fly box. It uses powerful magnets under a dense plastic that won't wear and tear from switching flies.”

The Eddy launches November 16, 2026. Pre-orders are open now at $44 — reserve yours.

Hooks Up is for size 16 and smaller nymphs — down to the microscopic size 24s. Hooks Down handles eggs, worms, euros and big beads. Standard is for size 14+ nymphs and dry flies. It's built for small flies and works just as well for any fly in your box.

300+ in a real-world mix: dries, nymphs, soft hackles, eggs and euros, each with a home of its own across two sides. Go all-in on size 16 and smaller standard nymphs and it docks up to 674. Flies not included.

Yes. The closure is water-resistant and the box floats if it goes overboard. In our drop test, even with one side popped open, the latched side acted like a big bubble.

The Eddy has a limited lifetime warranty covering manufacturing defects and premature functional failures. No registration needed, and US shipping is covered on approved claims. Read the warranty.

Yes — 30-day returns on unused boxes, with no restocking fees. Return shipping is paid by the customer. See the returns policy.
