These are used PP bands. I was reusing them because I felt it was a waste to throw them away, but I've accumulated quite a few, so I'm listing them. There are 30 loops, each about 80 cm in circumference. There are many yellow ones, but there might also be some blue, brown, or white ones. The widths are varied, around 1 to 1.5 cm. If you are looking for specific widths or uniform items, please purchase new ones from a store. I will be sending reused items, so please only purchase if you understand this. Thank you.
