I play Netrunner, so I have to carry two decks with me to play. I have seen a lot of deckboxes, but these are the best. The plastic is durable. It seals shut with a magnet. Inside the box the two smaller deckboxes can be removed giving you easy access to put cards in and out. The colors are bright and fun.
The only problem with these is that they put their hideous Monster Protectors logo all over them. Nobody wants to see that. I have to cover them up with stickers to personalize. I would still much rather have a solid color box with no logos on it.
