Piece Keepers are magnetic trays that snap together, hold your components, and let you stand the box on its side without anything spilling. Here's a look at how they work.

Terraforming Mars ships with more bags than a grocery run. Every session starts with untangling them and ends with stuffing them back.
Eight Singles, six Doubles and two Unity Vault Lids later, the components have a place. Lids on, box closed, nothing rattles.
Before

Fair question if this is your first visit. Piece Keepers are magnetic containers for your board game components. Magnets on every side, so they snap to each other and stack inside the box without sliding around. The smokey translucent finish means you can see what's inside without opening all of them. You fill them once, drop them in the box, and next game night your Terraforming Mars cubes are right where you left them instead of loose in the bottom of the box.
No inserts to cut, no foam, no glue. Just containers that hold their place.
The small stuff. Meeples, coins, resource tokens. There's a divider inside, and it comes out if you'd rather have the full space.
Bigger tokens and tiles. Holds standard and half size cards, and fits sleeved standard cards as well.
Snap across a row of containers to lock them into one portable unit.
Every face has magnets. Trays snap to each other and to the lids, and they hold.
That's the part people pick up at conventions and don't put back down.



Lid off, tray out, start playing.
Group a stack under one set of Unity Vault Lids and the whole stack travels together. Put all your resources in one stack and setup becomes handing one thing to each player, instead of digging through a box and sorting.
Teardown is the same in reverse.
Every one of these is a real shelf copy, photographed after it was organized. GameKeeper has the exact counts for a growing list of titles, so you can check yours before you buy.

"I arrived home after Dice Tower East and the first thing I did was organize Wondrous Creatures using my new magnetic containers from Piece Keepers. What a joy! It’s so cool that I can take the container that holds the energy tokens and nets perfectly and place it directly on the game board for play."

"Absolutely love this find. The product is unique and so practical. The owner was so kind and pleasant to work with. Helped make my Origins Game Fair experience awesome."

"These are the best game piece organizers I’ve found yet! The magnetic connection makes it easy to combine them in ways that fit securely in the box or align in a straight row that acts as a piece library during gaming."

Most people start with the Squire's Satchel and cover one or two games, then add more later. If you want to check a specific game before buying, GameKeeper will tell you what it takes.
They're not cut for one specific box, so they work across your shelf rather than in a single game. GameKeeper has the counts for a growing list of titles.
