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.

Neat and Square
Color: Black, Size: Square
This turned out to be durable and looks good on my valet table. The difference in the way it snaps to the sides, keeps the corners square and looks better than the other models that force the corners to extend outward.
