Build quality is decent, magnets hold the case well. However! Once you load each card slot with 1 card in each slot and put a few dollar bills in the wallet, the wallet will not close. Obviously cards and cash add more bulk, that's part of the problem, but another factor is the clasp they put on to keep the wallet closed, it's too thick even with no cards or cash in the pockets. See photos. Really very bad design. In addition to this main problem, another problem is that this item is very bulky and inconvenient to put in the front pocket of your trousers. I will return it and look at other options. A few design changes and it could be a much better product. Update: I decided to keep it and see if I can get it to work. I removed the fastener and replaced it with self-adhesive Velcro. Much better! In fact, it now closes and is now a lot less bulky. Still bulky, but not that bulky. At least now it can be used. I'm keeping it until something better comes out. I'm leaving two stars because I still feel like it's a bad design and I didn't have to change it to make it work, it should work best right out of the box.
