Well built, minimal and modern
Color: Moss Green, Size: 9.5in x 7.9in
Bought this to help build routine for my son, rather than spending inordinate amounts of time looking for his things. It’s quality built with a sleek modern look. Very handsome.

Excellent tray
Color: Sand Brown, Size: 9.5in x 7.9in
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.
