Colman and Company searched long and hard for the right manufacturer to work with in producing these very high quality hotfix rhinestones. Good clarity, consistency and quality of glue/adhesion are what you can expect from any of our Rhinestones, Rhinestuds or Nailheads as a result. All of our Rhinestones are hotfix so have the glue already attached and require heat from a press, hand iron, or a rhinestone embellishment wand like our Glitz Up tool for application. Rhinestones are available in bags of 50 gross, which is 7200 stones. Larger quantities are available under our Wholesale Program.
