I've been using a Quiver Card Case and I've been looking for a deck box that fits inside while holding my double sleeved cards. I'm considering purchasing a Ultimate Guard Boulder 100+ Deck Case to store my double sleeved cards in. The product description says:
Designed for 100 double-sleeved or 120 single-sleeved standard sized cards
Inner Dimensions: 68.5 x 67.5 x 93 mm
However, I've been double sleeving my cards with Dragon Shield Perfect Fit Sealable inner sleeves to really protect my expensive cards. These inner sleeves have a design where the sleeves fold in on themselves to seal the card inside the inner sleeve. This makes the thickness of the inner sleeve one extra layer thick.
Since I don't have the product on hand, I'm unable to test exactly how many of my double sleeved cards might fit inside the deck box.
These cards are for Magic: the Gathering, so typical deck sizes are 100 cards or 75 cards. I don't think I'll be able to fit in the 100 cards, but might I still be able to fit the 75 cards inside?
