I'm selling these items because my child has outgrown them. The gray one is 90cm, and the banana-patterned one is 95cm. Both have been used, but the gray one shows more wear. The banana-patterned one is in good condition with less wear and tear. There are no noticeable scratches or stains. Would these be suitable as spares? These items have been used by a child. Please understand this before purchasing. Feel free to ask any questions in the comments. Thank you.
