I purchased this to better contain all the stuff I keep in my pockets when I change pants. I keep it on my nightstand. The size is perfect for my needs. It seems fairly well made. However as others have mentioned, the bottom rubber lining arrived slightly delaminated. In my case, it’s not a huge issue as the area is a very thin line. I would recommend that the manufacturer do a little better job with the gluing process during assembly and pay more attention performing a QC check. Other than this small complaint, I am satisfied with this tray.

Pretty good product!!

Color: Dark Brown

This wooden valet tray is exactly what I needed for my new apartment. It surprised me how big it was because I wasn’t expecting it to be that big. Overall, this tray is good and holds all my things!
