3 Rings made out of antique buttons. Actual 'ring' part is made out of plastic that has some give (somewhat adjustable). Open to offers, or creating a separate listing if you're only interested in one or two rings (just let me know). **SIZING: Because these are somewhat adjustable I can't provide an exact ring size. They all fit my middle finger which is a size 9, as well as my ring finger, which is 5.5 cm (between a 7-8) because the plastic can be manipulated. Keep in mind before purchasing!
