Small touch, Big in Style
Color: Gray
Perfect size for a cup of tea/coffee or a glass of wine on the side
Also great for placing a piece of jewelry or anything else you want close by your bedside
I like the oval shape better than a rectangle one and the quality of material is top notch, not to speak of how strong it is…a really good buy for us!

Durable Valet Tray
Color: Black, Color: Black
LOVE this leather valet tray. It’s a very well structured piece that seems like it’ll last. The leather looks flawless and is rather durable. I couldn’t be happier to finally have a place for my husband to drop all of his stuff from his pockets when he gets home from work.
