Versatile and decent size
Color: Black, Color: Black
I love little trays for random things. I saw this and had to get it. I ordered the black one. It came nicely packaged in a box that protected it from any damage during transport. It is approximately 8” x 8” x 1.6.” It is made of faux leather and MDF. It is supposedly water-resistant, but I have tested that. The interest in smooth, while the exterior walls have vertical ridges. The bottom is smooth. It’s heavy enough so it doesn’t side around. I have used it for numerous things: jewelry, pens and notepads, keys and sunglasses, perfume, medications, change, remotes, and change. It’s a handy and modern piece that could suit most people.

Small Valet Tray Nightstand Organizer (Black)
Color: Black, Color: Black
I really love the leather look of this valet tray. It’s both stylish and functional, giving a classy touch to my nightstand while keeping small items neatly organized. The PU leather finish feels smooth, looks high-end, and the construction feels sturdy. Pros: Elegant PU leather design with a textured finish Compact 8x8 inch size fits perfectly on nightstands, dressers, or desks Multi-purpose — great for keys, watches, jewelry, remotes, or glasses Water-resistant surface makes it easy to wipe clean Adds a decorative touch while being practical Makes a thoughtful and stylish gift Cons: The sides are a little low, so bulkier items may slide out Only available in limited colors compared to some other organizers Overall, this is a really nice valet tray. It looks more expensive than it is, keeps my essentials in one place, and adds a clean, organized look to my space. Definitely worth it if you like the leather aesthetic!
