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!

Quality is top notch!

Love it. Larger than I thought it would be but looks great and just what I needed. Just wanted something on table when I come in the door for my keys, charger, etc… Has a large storage capacity. Lasting the quality is amazing. Would buy again in a heartbeat!

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.

Understated valet tray
Color: Gray, Color: Gray
I like the clean lines and simple shape and the unobtrusive stitching. I'm not crazy about the seam of where the sides of the tray meet, but if the tray is filled, it's not as noticeable. It's a nice catch-all to keep my desk clutter-free!
