Such a good price!
Color: Dark Carbonized Pine, Size: 16.5 x 6.1 x 0.59 inches
Love them! They are so cute, couple notes. The wood doesn’t come with pre drilled pilot holes for attaching the brackets so you will need a drill/drillbits. It is real wood which impressed me, but outside tools definitely required. Including a level!! The “level” they offer is indeed a bubble in liquid, but it’s about an inch long, 1/2in wide and a cylinder so probably the most useless, cutest level I’ve seen in my life. Otherwise great! They hold exactly what I need.
