I love this storage case. it was much cheaper than name brands and its constructed well. I've had it for about 6 months and held up perfectly. I've knocked it off my desk at a dozen times and it's survived. it also withstood a trip to a Regional, but I drove so I can't speak for it's ability to withstand flying in a checked bag.in terms of size, for Pokemon TCG, each side fits 5 of the thin ultra pro deck boxes with a small space left (the perfect size for a dice box!). the licensed ultra pro deck boxes made of thicker material also fit the correct way but they're a little snug. (I think 5 will fit per side, but I don't have a 5th to test with. at least 4 will fit, definitely.) you can also fit a pokemon center deck box in neatly if you turn it 90 degrees. and I have a card guard deck box from Target, I believe it's for 80 or 100 cards, that will take the space of 1 ultra pro box and the small space left over (see image).the material inside the lid is nice and soft and I love the color. when you fold the lid out, it's not enough space to play a game on, but you can definitely pay your deck out on the lid to check it. also, I have the litter boxes in my office, and all the times this case has fallen on the floor... the leather-like outside hasn't gotten scratched by litter once.over all, it definitely keeps my decks secure and organized, and its a great value for the price. I'd highly recommend it for PTCG players.
