Wooden, rounded-corner rectangular bath mat, approximately 30cm x 40cm in size. - Size: Approximately 30cm x 40cm - Material: Diatomaceous earth - Shape: Rounded-corner rectangle Unused I bought this because the bath mat at my house wasn't absorbing water at all. However, after using sandpaper, the water absorption improved, so I'm selling this because I ended up not needing it. I used the sandpaper on this product, so the sandpaper is not included.
