Nickel-free: an ideal choice for persons with nickel-allergies or for creating jewelry for countries with a ban on certain products containing nickel.

Waterproof: great for fiber crafts, jewelry and sewing where items may get wet or need to be gently hand washed.

Heat resistant: a great embellishment for use in low heat projects (under 275 degrees): bake directly into polymer clay; adorn lampshades, hot-glue into scrapbooks. Note: certain colors (primarily copper) can change slightly when heated so advance testing is always recommended.
