I am selling this item because my child outgrew it without ever wearing it. * Size is 50cm. * I am also selling a chair belt separately. Please take a look if you're interested. * Please understand that this is a used item. * Please note that it may be slightly compressed for shipping. * Please be aware that there may be minor scratches or stains due to my amateur inspection and storage. Therefore, there may be some oversights. I apologize, but please refrain from purchasing if you are very particular about the condition.
