Thank you for viewing. Used only once and in clean condition. I purchased it thinking it was 21cm, but it's small, and I think it's for children around 20cm. The main body says 32. The belt can be adjusted in 3 stages. Since it is a used item, there is a feeling of use and some scratches. Please refrain from purchasing if you are concerned about odors or minor details. I will ship it as compactly as possible. There is a possibility of changing from Rakuraku Mercari delivery to Yu-Yu Mercari delivery.
