This RAW Back-Flip is made of striped natural and dark bamboo. The color, form, and size depend on the type of wood – all trays are handmade. The central piece is held together by a strong magnet to allow the tray to be split in half and easily reattached! The main platform has rounded edges just like our metal trays, and the bottom has foam on each corner to avoid scratching any surfaces. There are 4 round holes at the top Sizes of holes from left to right (approx.): 60mm, 35mm, 16mm, 52mm Box size in the photos
