Comes with 10 sets of snaps and 10 34ss coordinating crystals. A Snap Setter is required for application of the snap. The fabric will show through in the center and is where the crystal is adhered to after the snap is in place.
When I apply a 34ss Swarovski Crystal, I hold the crystal with a pair of metal tweezers and hold the crystal over a lighter or candle for a few seconds to heat the glue. Place it on the fabric immediately and press the crystal down while the glue is still hot for permanent adhesion.
