Very nice nightstand organizer
Color: Bootlegger Brown, Size: 10.5" x 7" x 1.5"
I was looking for a way to keep all my essentials together at the end of every day, so I had started looking at valet trays. These caught my eye as they're rawhide that are offered in a few different tones. I chose the Large in the Bootlegger Brown tone as it goes with pretty much every decor and suits my style. It's a great shade, and the color is rich.
The size is perfect for my needs. Watch and ring at one end, phone on top of slim wallet on the other, and two small sets of keys in the middle. Not crowded, but also no wasted space. The leather is very thick, and the tray keeps quite rigid, despite its size. The edges are turned up just enough to contain your items, but not so much that you feel like you're digging down into something.
One minor gripe: I wish the bottom were somehow weighted to keep the tray from "wiggling" when grabbing items out of it. It would make for the perfect tray. I may try to affix something under it that's flat and heavy (but thin), so I'm not too worried about it. Overall I believe this is a fantastic product. I would recommend this for anyone who carries at least a half dozen EDC items as you're sure not to forget anything when preparing to head out for the day.

Good Coin / Keys Tray
Color: Midnight Black, Size: 7.5" x 5.5" x 1.5"
Loved this organizer so much that I ordered one for my Grandson for Christmas. Coins and keys don't make noise when dropped into the tray and it protects the wood of our dresser. Looks very nice too.
