ポーカー用ダブルデッキカードボックス - クリアアクリル製（2.5 x 3.5インチカード対応）

Kept my two setups of tournament-size cards snug and fingerprint-free at the table. The acrylic is thick enough that it doesn't flex when you slide a deck in fast, and the clear finish actually makes it easy to spot which deck is which mid-game.

You can see right through the clear acrylic to grab the exact deck you want, which is so handy when friends are dealing. It holds two standard poker decks snugly without any rattling around, and the lid closes firmly enough that I trust it in my bag.

Finally found a case that actually fits two standard poker decks without squeezing them in. The acrylic is crystal clear so I can see which setup is inside at a glance, and it snaps shut securely enough for my backpack. Threw it in my gym bag for a week and the cards came out pristine.
