This is a bubble machine with a strap that makes sounds and lights up. I purchased a set of two online and only used one. I am selling the unopened and unused one. The first photo was taken with the used one in front to show the contents, as the item will be shipped unopened. Therefore, the item will be shipped in the unopened and unused condition shown in the second photo and beyond. There was no screw for the battery compartment, so I contacted the seller, and they said it was originally designed that way. I assume the unopened one also does not have a screw. It snaps into place, so there were no problems using it. Shipping is planned via regular mail (660 yen), but this may change. Please note that I am not responsible for any loss due to misdelivery, etc. I try my best to check the item carefully, but please forgive any oversight as I am a private seller. Returns and complaints are not accepted after purchase.
