Swarovski Flatbacks Article #2058 in the size SS10 (between 2.8 and 2.9 mm).
The color is Light Siam Red, a bright, holiday red.
These are the plain flatbacks with no adhesive.
I generally use E6000 orGem Tac to adhere them, depending on the surface, of course.
They are the Advanced Crystal Swarovski Crystals, and are lead free.
You will receive 50 pieces.
A lovely addition to your dance costume!
