Amazing well thought out tray

Super well thought out tray. Looking amazing of course and the sizes of the slots are great. I can fit my large phone in the slot and it has a space for the charger on both ends. Love this tray.

Really nice!
Color: Brown
Nicely made. The wood has a lovely finish and rich color. The compartments have a softer bottom so you don’t have to worry about scratching your glasses or other surfaces. Great assortment of compartment sizes to help organize your items.
Kicking myself for not getting one sooner.
