Turn ordinary items into eye-catching pieces with a high-volume rhinestone assortment designed for hobbyists, makers, event decorators, and nail artists. This kit bundles 31,000 black flatback resin crystals in five sizes (2, 3, 4, 5, 6mm), a 24-grid storage box, a wax-tip picker tool, a user pamphlet, and three 10ml tubes of B7000 clear glue with precision tips. The stones are faceted to reflect light and are intended for glue-on application to fabrics, accessories, cosmetics containers, glass, and more.

How do I apply these rhinestones cleanly and securely?

Application is straightforward: clean the surface, apply a small dot of B7000 glue, pick a gem with the wax-tip picker, and set it in place. Allow 10 minutes for initial setting and up to 48 hours for the bond to fully cure for best durability.

• Use the included extra-fine metal-tipped glue tube for pinpoint adhesive placement.
• Work in small sections to avoid glue drying before positioning stones.
• Press gently for a few seconds to seat the flatback rhinestone before set time.
• Let projects cure 48 hours for maximum hold, especially on fabric or items handled often.

Which materials can I safely decorate with these flatback crystals?

These resin rhinestones are intended for glue-on use to non-porous and porous surfaces alike, including fabric, plastics, metal, glass, and wood. Choose the right glue and prep the surface to ensure long-lasting adhesion and to prevent discoloration or lifting.

• Fabric and costumes: use B7000 and allow full cure before washing or heavy wear.
• Glass, plastic, and metal: the clear adhesive bonds strongly to smooth surfaces.
• Nail art: use small rhinestones for press-on nails; avoid direct skin adhesives.
• Party décor and accessories: ideal for tumblers, phone cases, sunglasses, and caps.

How are the rhinestones organized and what sizes are included?

The set is organized into a 24-grid transparent storage box so you can quickly find sizes and keep leftovers neat. You receive a mixed bulk supply arranged by diameter: 2mm, 3mm, 4mm, 5mm and 6mm—sized to layer, fill large areas, or add tiny accent points.

• Five size options let you create gradients, outlines, and dense coverage.
• 14-facet resin cut enhances sparkle under light for a gemstone look.
• Large piece count (31,000) covers multiple projects without restocking.

What does the included B7000 glue offer for DIY projects?

Three 10ml tubes of B7000 adhesive provide immediate tack and long-term bonding for a range of materials. The formula dries clear, features an extra-fine tip for accurate glue placement, and the metal nozzle reduces clogging for continuous use.

• 10-minute initial set time; 48 hours for full curerecommended for durability.
• Clear finish prevents visible glue residue around black stones.
