● I prepared it, but it wasn't used, so it's practically new. ● This is a silicone sheet tray that is easy to carry. It's convenient for outings and travel, as it can be folded up small. Made of silicone, it can be easily washed clean if it gets dirty. ● How to use: Place a pet sheet on the tray and insert it into the four side stoppers to prevent it from slipping. ● Pet sheets: One regular size sheet can be used. ● It will be shipped via Yu-packet, so the box will be flattened to A4 size for shipping.
