JUST fits 50 sleeved cards
I use these to hold 50 card decks single-sleeved in dragon shields and they fit very snugly. I don't think a 51st card would fit. It makes the cards feel very secure and helps press the air out of the sleeves. The clear boxes make it easy to see what deck is in them and they feel very durable. I'd definitely buy them again.

Can confirm: holds 40+ standard cards. Exact numbers in review.
I was able to squeeze 50 sleeved standard sized cards into the box, but no more than that, so don’t expect this to work for a Pokemon deck. As for unsleeved, I was able to get 96 cards in the box, but MAYBE you could push that to 100 if you really weren’t worried about damaging them. I had hoped to get 60 sleeved in there, but knew that it was meant to only hold 40. I wish there was a size between the 40 and the 60 to really snuggly fit my deck into as I like my deck boxes being as low profile as possible and LOVE ultimate guard. Oh well, I can dream.

Great deck box for revised 40, A40, and FE40 decks.
I love the thick and sturdy construction of these ultimate guard boulder 40+ deck boxes. There’s ample room for a double sleeved 40 card deck and they stay securely closed. I have some of the soft touch colored versions too, but my favorite are the clear, so I can quickly see what deck I’m grabbing. It’s an exceptional value, and great quality product for anyone looking to protect their decks!

Odd white stain
There is an odd white stain in the front lip of the plastic, I put my finger on it to make it a bit more obvious. Other than that the product is fine

Great quality and price boxes!
I love these boxes and have many colors and sizes. They fit perfectly into my Quiver case and are super sturdy to protect all of your cards. They also fit the amount advertised when they are double sleeved! I am super happy with this line of products and will continue to use them!

Prodotto ottimo. La qualità si nota tutta, resistente e solido. Ci stanno esattamente 41 carte con doppia sleeve (perfect e normale). Molto tascabile. Adatto per portare mazzi di yu gi oh basilari senza extra e side.
