Smart Kid Belt Meteor, set of 2. There are no major stains, and I think they are clean. Used for about 2 years. After that, they were stored at home for 2 years without being used. I am selling them because I no longer need them. The instruction manual is not included, so only the items themselves will be sent. Please check the usage instructions on the web, etc. These were used by children and are second-hand items. Please purchase only if you understand this.
