BELLEBOOST 5mm Black Resin Rhinestones 2500pc Pack — Flatback SS20 Jelly Gems with Tweezer & Pickup for Nails Crafts Tumblers

BELLEBOOST 2500-piece pack of 5mm black flatback resin rhinestones — lightweight jelly gems for decorating nails, crafts, tumblers and large designs.

These small, round resin gems are sold by weight and come in an abundant quantity ideal for repeated DIY projects, event decorations or professional nail work. The pack contains roughly 2500 SS20 (5mm) black jelly rhinestones plus a tweezer and a pickup pencil to help place each stone precisely. Because they are non-hotfix flatbacks, you will need adhesive suited to your surface: craft glue for objects and nail glue or UV resin for manicures.

How do these rhinestones perform on nails and small nail art pieces?

The 5mm size is popular for statement accents and 3D nail art; the flatback shape makes them easy to glue onto polish, acrylic or gel. Their resin composition keeps them lightweight so they’re less likely to lift, while the faceted cut creates a glossy, jewel-like reflection under light. For secure results, use quick-dry nail glue or UV topcoat/gel burial when appropriate.

• Size: SS20 / 5mm — suitable for accent nails and cluster designs.
• Material: durable, lightweight resin that resists chipping.
• Application: use nail-specific glue or embed under gel/UV topcoat.
• Included tools: tweezer and pickup pencil for accurate placement.

Can I use these gems for tumblers, phone cases and larger craft surfaces?

Yes — the large quantity and uniform size make these rhinestones practical for covering broad areas, creating gradients or detailed patterns. They adhere well when bonded with strong craft adhesive such as B7000 or E6000 and produce a consistent black accent across accessories like cups, phone cases and decorative frames.

• Bulk count (≈2500) supports full-surface or large motif projects.
• Flatback shape sits flush on curved or flat objects when glued correctly.
• Recommended glue: industrial-strength craft adhesives for durability.
• Great for coordinating with other sizes or colors for layered effects.

What are the best tips for handling and applying these flatback resin rhinestones?

Working with tiny gems is easiest when your workspace is organized, clean and well-lit. Use the included tweezer and pickup pencil to avoid touching adhesive with fingers. Apply glue in small dots or lines, place each stone carefully, then allow full cure time per the adhesive manufacturer to ensure long-lasting hold.

• Prep: clean and dry the surface before gluing.
• Tools: use the supplied tweezer and pickup pencil for precision.
• Glue choice: quick-dry nail glue for nails; B7000 for crafts.
• Curing: follow adhesive instructions for complete setting time.

Will the black jelly rhinestones match other colors and finishes?

Black resin gems work as a bold neutral and pair well with metallics, pastels and bright hues. Use them as contrast anchors in colorful mosaics or as subtle accents on monochrome designs. Their faceted surface offers a soft shine rather than a mirror finish, which blends elegantly with many materials.

• Versatile contrast: pairs with gold, silver, white and vivid tones.
• Finish: jelly-style shine that complements matte and glossy bases.
• Design flexibility: use alone for minimalist looks or mixed for depth.
• Mix-and-match: suitable with other sizes/colors for gradient effects.

Who is this for? Crafters, nail technicians, small business makers and hobbyists who need a large supply of consistent-sized black flatback gems will find this BELLEBOOST pack useful. It’s tailored to anyone creating repeat projects — from custom drinkware and phone art to event decorations and professional nail sets — who values quantity, easy placement and a jewel-like finish without the weight of glass or crystal stones.
