These are teardrop-shaped acrylic stones. They can be used to decorate various costumes, such as those for rhythmic gymnastics and social dance. Compared to glass rhinestones, they are lighter, so replacing or combining them with glass rhinestones will reduce the weight of the costume. They also have good color development and adhesion to adhesives, making them very easy to use. The back is flat, and they are the type that is glued on with adhesive.
