This 10 gross package of 9ss (2.5mm-2.7mm) Swarovski® 2058 Xilion Rose flatback rhinestones in Crystal are small, glue-on stones that are clear, colorless, and uncoated: pure sparkle with nothing between the light and the facets. With no heat-activated backing, these flatbacks are set with a fabric or craft glue and a pickup tool. At 9ss, this small stone bridges the gap between the extra-small detail sizes and the more common 10ss, making it a strong choice for outlines, fine accents, and filling between larger stones on costumes and performance pieces.
Best for: outlines, fine accents, filling between larger stones, and adding depth to mixed-size designs on dance costumes, skating dresses, cheer uniforms, pageant pieces, and western wear.

FAQ
What is 9ss in millimeters?
9ss rhinestones measure approximately 2.5mm to 2.7mm.
What color is Crystal in rhinestones?
Crystal is clear and completely colorless with no coating. It adds bright sparkle without introducing any hue, making it the most versatile rhinestone color for any fabric, palette, or design style.
What size rhinestones should I use for costumes?
Most costume makers build around 20ss as the main all-over size, fill with 16ss, and accent with 30ss or 34ss so the design reads from a distance under stage lights. Smaller sizes like 9ss work well for outlines, fine accents, and filling between larger stones to add depth to a mixed-size layout.
What glue should I use for flatback rhinestones?
Gem-Tac works well for most fabrics, and E6000 is a strong option for trickier materials like synthetic suede and velvet. Always test on a scrap first to check adhesion and dry time.
