Frequently Asked Questions

Q2. How many Magnetic Card Holders fit inside?
A2. It can hold 32 YOROI Magnetic Card Holders, or 31 when each holder is placed in a protective bag.

Q3. What materials and texture does it use?
A3. The exterior uses PU leather for a premium, comfortable feel. The interior uses a soft material designed to help protect cards and accessories from scratches.
Q4. Which card games are compatible?
A4. It is suitable for cards from standard-size TCGs such as Pokémon TCG, MTG, Weiß Schwarz, ONE PIECE Card Game, Disney Lorcana, and GUNDAM CARD GAME.
Q5. Does it really hold 500 cards?
A5. Capacity varies depending on sleeve type and card thickness. With thin sleeves, it can hold up to approximately 500 cards. With character sleeves or thicker cards, approximately 300–450 cards is a more realistic guideline.
Q6. How should I store the box, and when should I replace it?
Store it away from high heat and humidity. The polyurethane in the PU leather exterior naturally deteriorates over time as it reacts with moisture in the air. In Japan's humid climate, we recommend considering replacement after about three years. Actual lifespan varies with storage conditions.
