My child loved Non-Tan, so I made two of these for toilet training. They are approximately 25cm x 25cm. I'm selling one because it wasn't used. They are made with colored construction paper and laminated. When I said, "Let's go to the toilet because Non-Tan is there!" my child was happy to go, and the training went smoothly. It depends on the child, so just for reference. I will disinfect them with alcohol before shipping. Please consider purchasing if you understand that they have been stored at home.
