Just lovely
Size: 8.5" x 5.8" x 1.9", Color: Orange
Purchased this several months ago and liked it, but I had received so many complements on this tray since then I had to submit this review. The tray is sturdy and put together well, and the size is exactly what was given before purchase.

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!
Color: Black
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!
