Thank you for viewing! I purchased this authentic Japanese product at a store in 2019. I used it for my older child and younger child until they were about 1 year old each. It shows some signs of use. [Important Notes] One of the fasteners is damaged. (Photos 8, 9) You may be able to have it repaired or, if you are good at sewing, replace it with a new fastener and sew it on with a sewing machine. However, please do so at your own risk. Please do not use it as is, as it could lead to an accident. Please purchase with the understanding of this condition.
