BELLEBOOST 4mm Black Resin Rhinestones Bulk 4,000pc — Flatback Jelly Gems with Tweezer & Pickup Pencil for Nail Art, Crafts, Tumbl

These are 4mm (SS16) black flatback resin rhinestones — a 4,000-piece bulk set with a tweezer and pickup pencil, ideal for bedazzling nails, crafts, tumblers and large-area designs.

BELLEBOOST’s 4mm black jelly rhinestones are lightweight, faceted resin gems sold by weight so you get roughly 4,000 pieces per pack. They are non-hotfix flatbacks, meaning they require adhesive to attach, and their polished facets give a bright, jewel-like sparkle without the cost or weight of glass crystals. The kit includes simple tools to help you place each gem precisely.

How do I attach these rhinestones to nails, tumblers, or fabric?

Because these are non-hotfix flatback resin stones, you must use an appropriate adhesive for each surface. For nail art, thin UV or quick-dry nail glues hold best; for craft surfaces try a strong jewelry or fabric glue like B7000. Always clean and dry the surface, place the gem, then let the adhesive cure fully.

• For nails: use UV or quick-dry nail glue; cure as instructed.
• For tumblers and mugs: use strong clear-drying glue or epoxy and seal edges.
• For fabric or clothing: use flexible, fabric-safe adhesive and press firmly.
• Tools included: tweezer and pickup pencil for precise placement.

What projects work best with a 4,000-piece pack of 4mm black gems?

This large quantity is suited for projects that need many identical stones or for making patterns and gradients. Use them to fully pave small to medium areas, add repeating accents, or keep a steady supply for multiple nail sets, party decorations, and craft sessions.

• Pave designs: phone cases, cups, or small panels of diamond art.
• Bulk nail art: salon sets or several client applications.
• Event decor: masks, headbands, or costume embellishments.
• Mixed-media crafts: scrapbooks, keychains, and guitar inlays.

Are these rhinestones durable and easy to work with?

Made from chosen resin, these jelly rhinestones are lightweight and resistant to cracking under normal decorative use. Their flatback profile makes placement straightforward, while the faceted cut creates a lively shine. Note that because resin is softer than crystal, heavy wear without proper adhesive or sealing can reduce longevity.

• Material: resin — lightweight and economical.
• Finish: faceted cut for reflective sparkle.
• Shape: round, flatback — simple to glue down.
• Care: avoid abrasive washing; seal for items exposed to water.

How many pieces and tools are included, and what else should I prepare?

Each pack contains approximately 4,000 pieces of 4mm black flatback resin rhinestones, plus a tweezer and a pickup pencil to speed placement. Glue is not included, so choose adhesives suitable for your surface and intended wear.

• Contents: ~4,000 pcs 4mm (SS16) black resin rhinestones.
• Included tools: one tweezer and one pickup pencil.
• Not included: adhesive — use B7000, strong craft glue, or nail glue.
• Tip: sort on a tray to speed placement for large projects.
