OPL K9 Glass Crystal Loose Rhinestones - Hotfix Flat Top Rectangle Shape Iron-on Rhinestones for DIY Crafts and Decoration

Our OPL flat top rectangle K9 glass hotfix rhinestones are precision engineered for users who demand a sharp, clean geometric sparkle for their custom DIY projects. Made from high-purity K9 optical crystal, each 3x8mm standard rectangle stone features a perfectly polished flat top surface and 8 precisely cut side facets, delivering bright, uniform light refraction that creates a sleek, modern shimmer far more structured than regular round rhinestones.

Unlike low-cost glass rectangle stones that often come with uneven edges, air bubbles or faded cut lines, these K9 crystal rhinestones go through 3 rounds of manual quality inspection before packing, ensuring every single piece has zero defects. The industrial-grade hot melt adhesive coated on the flat back is washable and high temperature resistant, bonding securely to fabric, leather, wood, ceramic and most heat-stable craft surfaces in just 20 seconds under 130-170℃ heat press, no peeling, no shifting even after repeated washing or long-term display.
