It's a little lottery to find good device cases without touching them. I was looking that meet the following criteria: - Solid (no corners are split, the edges that curl) but not too thick. Great for those. - Although transparent, ideally invisible without being "Golden Girls" or too rigid. These are somewhat milky, but it will. - Generous dimensions (double albums with square back possible). About 32 cm square for them, fine. - Reasonable price per unit (I eat a lot). In the end, this is not the best, but they do work.
