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.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
