The two sides don’t fit together properly and pop open with the slightest of uneven pressure. There’s practically no clips to keep them together so cards just slide right out of them when picked up vertically. Don’t get this if you are looking for something to keep very expensive items in as they will just get ruined or lost. You get what you pay for.
