Stylish, well sized valet tray. Would highly recommend
Color: Brown Frame
Stylish valet for your dresser, desk or wherever you would like to place it. I got tired (and so did my wife) of me just emptying my pockets on the dresser at the end of each day. Junk would accumulate, change would accumulate and everything was all spread out. This tray is stylish and made of good quality leather. I really like the different size partitions making its storage capacity perfect and done so neatly. Now my items are organized and easy to grab the next day making it functional at the same time.

Simple and Super Useful
Color: Black Frame
This tray is great. It looks really nice on my desk and gives me one easy spot to drop everything—phone, wallet, keys, sunglasses, glasses, and whatever else I’m carrying that day. Keeps things organized and adds a clean look to the space.
