Firstly, I was very impressed by the packaging and attention to detail, from the box to the lovely wrapping. I purchased the brown and the tray is beautiful with the two-tone. I love the tree imprint on the inside. It looks very rich and the leather has a great feel to it. I also like that the logo was imprinted at the bottom/back. This would make a great gift. Great product!

Great for use atop the bedside table!

Very nice! I bought this for my father for his birthday, and he really liked the gift! It's a nice little place for him to keep all of his essentials together on the bedside table. No more losing his watch, keys, wallet, etc. or knocking them off the table!
