Nice Floating Shelves
Color: Oak, Size: 24" W x 7" D x 1.5" H (2 pieces), Color: Oak, Size: 24" W x 7" D x 1.5" H (2 pieces)
I wasn't sure how to fill this space between my kitchen cabinets, and I think these shelves turned out looking great and fit the space nicely. They were easy to install, good quality, and could handle a decent amount of weight.
