This is a voice toy that can be used for toilet training with Kodomo Challenge. I will also include two brand new batteries! By switching the panel up and down, you can hear Shimajiro and Mimirin's voices and songs, and receive words of praise, which increases motivation. My child initially hated the toilet, but started going in after I put this out (^^) It has been used, but has been disinfected with alcohol. Operation has been confirmed. ◆ Immediate purchase is OK! ◆ We are not considering price reductions. ◆ Please refrain from purchasing if you are particular about the product condition or seek perfection.
