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.
