Here are the challenge items: Irotti, the bus, and the cooking set. Irotti is like a Matryoshka doll, so it's easy to put away. I'm selling these because my child no longer uses them. If you are concerned about the condition or how they've been used, please comment. Please understand that these have been stored by a private individual, so they are not perfect. Please refrain from purchasing if you are looking for a completely flawless item. I ask for your understanding, as I've previously received complaints from buyers who didn't read the description carefully. *To prevent any issues, returns and complaints are not accepted after purchase.
