Lacey Carroll Interiors llc They are unfinished 2"x 2" x 8" lumber. Cut them into what ever lengths you need. I primed and painted them white. Attached them with screws from the front face and puttied the holes. I thought it was super cool and very cheap and easy. Tip: make sure you use a level when installing the shelves or obviously the cars would roll off the end. Ha!
