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.
