Premium MTG Commander Deck Box with Dice Tray - Holds 200+ Cards, 35pt Magnetic Holder & 2 Dividers - Perfect for MTG, TCG, CCG Card Storage & Game Nights (Blue)

I used this deck box for Yu-Gi-Oh! cards. The side window on this box is neat because if you have a lot of decks, you can put the main monster or card on the outside for easy identification. The window has a thick plastic protector that will keep whatever card you keep in there safe from scratches so you don't have to worry about having an expensive card on the outside of the case.The case is lined with a velvety material and has a magnetic lid that detaches to provide full access to the cards inside. The case also comes with two plastic dividers to separate the cards within. This works especially well with Yu-Gi-Oh! cards because you can separate your main deck, extra deck, and side deck in the same box and still have plenty of space for other cards.Speaking of space, this deck box is very wide. Not wide enough to turn your cards sideways but wide enough to fit the much larger Pokémon cards in there easily with room to spare. The extra room isn't always a good thing though. The cards can rattle around inside especially if the box is shaken. Make sure if you are using it for valuable cards that you keep them in a protective sleeve to keep them from rubbing together or having the corners bent. You can also pad the inside with something if you don't put in enough cards to fill the thing up fully. My 40 card deck with a 15 card extra deck with everything in card sleeves only filled a little over half of the box up. I could probably fit in about 30 more sleeved cards or if I didn't have the card sleeves I could easily fit ~100 cards in there.
