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.

Luxurious
Color: Sand Brown, Size: 9.5in x 7.9in
Firstly, I was very impressed by the packaging and attention to detail, from the box to the lovely wrapping. I purchased the brown and the tray is beautiful with the two-tone. I love the tree imprint on the inside. It looks very rich and the leather has a great feel to it. I also like that the logo was imprinted at the bottom/back. This would make a great gift. Great product!

Cable management
Size: 1/2inch x 164ft, Color: Black
Used for cable management. It's really good for bundling cat5 and cat6. But I doubt it would be very good for towing a truck. Maybe use rope or a chain... I don't know I'm not a cop.
