Very well-made, nice valet, solid wood with a silicone surface
I really do love this white BROWN wooden valet Tray. It has taken it place right next to my bed on my nightstand. Currently it contains a flashlight, my watch charger, earbuds, remote control, and a walkie-talkie. They all fit perfectly, it really keeps my stand, neat and clean looking. I like these trays because they look so much better than things just laying randomly across your nightstand. It saves things from rolling off to the back of the nightstand against the wall, where I have to flex like an acrobat to reach them. These are perfect for any works surface as well. These would be welcome in the shop. I'm sure they would be great for a teacher, a kitchen a professional at their desk. Just about anywhere you need to put small items and store them temporarily. One of the best things about it is that the bottom or at least the inside surface where you place items is not wooden. It appears to be some type of a silicone so you don't hear that wood sound when you drop things into it. It's soft and things don't roll or slide. It holds them in place exactly where you put them. The bottom came with four felt pads that you can stick on the bottom before you put it on your nightstand or wherever you're putting it. Keeps it from scratching any wooden surfaces. It has a nice rounded edges are very clean dark wood look and a great silicone mat on the inside, this is perfect for your nightstand. I really do enjoy it. Comedy no assembly required. It's well-made and it's a sturdy piece of wood. I highly recommend it.
