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.

Holds hubs personal items nicely.
This is a decent sized wooden tray for the price. The manufacturer took care to package this nicely so it was not damaged in transit. All the material used on this tray seem to be pretty decent. The color is very versitile. The wood feels durable and not a soft wood that would easily scratch or dent. The faux leather lining is very nice and makes it quiet when hubs puts his keys down. This tray comes with 4 feet which one must apply by simply peeling the release paper and sticking to the bottom of the tray. This is nice so the tray does not scratch the night stand. Honestly, this tray is very versitile as this can definately be used on an end table in the office or in the bathroom to corral items on the counter top. This is a decent product at a very fair price.

Beautiful and Functional Desk Upgrade
Color: Pink Marble-31.5"x15.8"(with Wall Charger)
I absolutely love this Pink Marble Mouse Pad with 15W Wireless Charging. The design is beautiful, soft, and feminine without being too much, and it instantly makes my desk look more polished and organized. The large size is perfect because it gives me plenty of room for my keyboard, mouse, notebook, and other desk essentials while still keeping everything looking neat. The wireless charging feature is such a convenient bonus. I love being able to place my phone down and charge it while I work without having extra cords everywhere. The surface is smooth, my mouse glides easily, and the pad feels comfortable during long hours at my desk. Overall, this is a great mix of style and function. It is perfect for a home office, gaming setup, content creation space, or anyone who wants their desk to look cute and stay practical. Highly recommend!

Works Well and Good Quality
Color: Black-Stock Market-31.5"x15.8"(with Wall Charger)
The recharging feature works well for both phone and earbuds. Phone charges very fast. Great looking mousepad that has ample size for both keyboard and mouse. Mouse moves easily on the surface and is much better than using it solely on a tabletop. Great price too!
