Set the fit. It stays there.
Drop the Anchor into your box and turn the core until your cards are held firmly upright.
No spring pushing back. No foam slowly giving up.
How it works
- Drop the Anchor into the empty space in your box.
- Turn the core to expand it until the stack is snug.
- It stays where you set it. Readjust any time your collection changes.
The contact plate stays stationary while you adjust, so it isn't dragging across card faces or sleeves while you dial in the fit. The open frame leaves room to tuck in a two-way humidity pack, dice, or tokens.
Why not foam or springs?
- Foam compresses and loses shape, traps humidity against your sleeves, and sheds particles as it ages.
- Spring dividers avoid the foam problem but push back with whatever force the spring decides.
- The Anchor does neither. The fit you set is the fit you get.
Will it fit?
The Anchor fills gaps from 59mm to approximately 84mm, roughly 150 to 210 single-sleeved cards. Treat those numbers as a starting point rather than a promise: sleeve brands vary in thickness, and double or triple sleeving changes the count substantially. If you want to be certain, measure the empty space in your box.
That covers bulk boxes, storage boxes, and cardboard row boxes, plus deck boxes carrying less than they were built for. Running three Commander decks in a case sized for four? The Anchor takes the empty slot.
Stackable: for wider gaps, use two or more.
