These are non-hot-fix flatback resin crystals, lightweight and faceted to catch light; they need adhesive for permanent application. The included tweezers and pickup pen speed placement so you can work faster and more accurately.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I attach these flatback rhinestones to nails and crafts?\u003c\/h3\u003e\n\u003cp\u003eBecause these rhinestones are non-hot-fix flatback pieces, use the right adhesive for the surface you’re decorating.
