This is an accessory for an inflatable baby bath! It's a stopper for the backrest (with removable double-sided tape) and the crotch area (with removable double-sided tape)! I'm listing it because I only used the main body (baby bath) and never used the parts mentioned above, so they ended up unused! I'd like to give it to you with the instruction manual included＾＾ Thank you for looking ♪
