These customizable, stretchy, and size-inclusive rings are made of glass and plastic seed beads which form a daisy chain. They are made with crystal elastic string and the knot is secured with super glue to be sure that it doesn't come undone.
These are not made of metal so should not tarnish on your fingers, however, avoid contact with water and hand sanitizer to ensure that the colors of the beads stay the same.
How to find your ring size:
There are $3 ring size measurers on Amazon and $1 ones on Etsy. You can also cut a piece of string/paper, measure the circumference of your finger, and look up what US ring size you would be online!
