Great gift
Color: Double-deck Black
Bought it as a gift, and he loved it. Nice, large size. Looks very nice. Love the drawer to hide stuff away so it doesn’t look so cluttered.

Nice valet!
Color: Double-deck Brown
This was a gift for my boyfriend. He loves it and immediately filled it with secret man things. Now, if I can just teach him to call it a valet. It is well-made and very masculine. I purchased the large one. Nice quality. Cool hidey holes.
