This is an exceptionally high-quality tray. The design was well thought out and it looks amazing. I keep it in my top dresser drawer to organize extra cards for my wallet, my watch, cufflinks, and other items. I can’t say enough about the high level of quality. It stays in place, has great storage and very reasonably priced I thought.
