Amazingly versatile
Color: E Black
Fun! It is really beautiful and easy to use. It is just about as big as your elbow to your fingers. It is great for necklaces and even bracelets and rings! It doesn’t shake unless you hang heavy necklaces on it. It is really stable otherwise though! It’s really easy to hang on the hook. If you have a clasp necklace, all you need to do is clasp it and put it on the stand. I’m amazed by the different types of jewelry you can put on, you can even put earrings on there but they might get lost so I don’t. Other than that so awesome!

Love the ability to have some of my more fragile items in here. A place where I can store without issue. The leather feels nice, it’s very sturdy, it’s a great black color, and I would get this again.

looks nice
Color: Brown, Size: 10.2" x 8.4" x 1.8"
Little smaller in person than I expected but the quality is very nice and the tray looks great on the coffee table. It holds eyeglasses, TV remote and other items I didn't want possibly scratching the table. It looks in person just like the photos.

Bought this for my husband's nightstand. He keeps his cologne in this and he loves the deep green color. The material seems very nice and the product is good quality.
