Best invention ever!! We have 3 dry erase boards in our house and expo low odor dry erase markers everywhere! I’ve never seen the caddy until now and I absolutely love it! There is not enough room on the boards for a set of markers and an eraser so this is perfect for us, and it’s so easy to use my kids  hung them without any help. Also the markers stay in the caddy pretty well along with the eraser without sliding out onto the floor.
