Large wholesale bag of 50 gross 3mm Clear AB Hot Fix Rhinestones. Iron on, Flat back. Wondering what AB stands for? Its Aurora borealis. Very colorful always changing. Bling your things with a color rhinestone that seems to pick up the color of the whatever it is placed on. Easy application with a home iron. No steam and a linen setting. Make sure the item you are putting it on is porous!Sometimes even a new t-shirt is not porous because of a coating they put on it! So always remember and never forget, doing the water drop test is best! If water absorbs then the hot fix glue will absorb. Otherwise use craft rhinestone glue.
