Stay Flat binder

Opens completely flat.
Even when it's full.

We know — there are already so many TCG binders out there, and yes, cute ones too. So what's special about a Bubble Mint binder?

Most zip binders have a round spine. The pages bow at the gutter, the book never sits fully open — and it gets worse with every pocket you fill. Stay Flat has a rectangular spine and no rings, so a full binder lies flat on the table like a gallery.

Bubble Mint started with a problem every collector knows: binders were made for trading, not for displaying the cards we protect the most. So we built the one we wished existed — for collectors who display, not trade.

Collector's guide

How to sleeve and protect a TCG card

Pokémon, Magic, One Piece, Lorcana — a standard TCG card is 63 × 88 mm. Here's how the layers stack, and which pages they fit.

  1. Inner sleeve — 65 × 90 mm. Slide the card in. It's a snug "perfect fit", so it holds the card still and keeps dust off the surface.
  2. Outer sleeve — 67 × 92 mm. Put the inner-sleeved card in opening-first, so the two sleeves open in opposite directions. That seals the card top and bottom.
  3. Prefer one layer? A single 66 × 91 mm sleeve fits a bare card and is the everyday choice for binders.
  4. Into the page. Every 69 × 93 mm pocket page in our store — 4, 6, 9 and 12 pocket — takes a single- or double-sleeved card.
