Flat Diamond plywood volume, is a pair of big 900mm long x 300mm wide x 90mm deep volumes

They come as a pair, so you can jam between them, use them as a horizontal break, layback from them in a corner, use them individually. The ultra low profile works great for using it as a break for your hands and really tough for your feet. Try it as a vertical crack or a pair of catching edges

Our volumes are made of 18mm plywood and have a textured surface
