TINKRSTUFF Resin Rhinestones for Crafting — 12,600 pcs 4mm Mixed-Color Flatback Gems with Tweezers

TINKRSTUFF 12600-piece 4mm mixed-color resin rhinestone kit is a large set of non-hotfix flatback gems with tweezers and pickup pen for decorating clothing, tumblers, nails and crafts.

If you make jewelry, customize apparel, or embellish tumblers and nail art, this kit supplies a broad palette of small, sparkling resin crystals to execute many projects without running short. The box contains 24 compartments holding approximately 12,600 pieces in a 4mm size, plus simple tools to pick and place each gem. These flatback stones are not self-adhesive, so you’ll pair them with glue for permanent decoration or temporary crafting experiments depending on your adhesive choice.

How many gems and tools come with the set?

The kit includes about 12,600 resin rhinestones organized into 24 grid compartments to keep colors separated and accessible. It also contains a pair of tweezers and a pickup pen to speed placement and reduce handling mistakes.

• Approximately 12,600 pieces total
• 24 storage grids for color organization
• One tweezer and one pickup pen included
• Each gem measures roughly 4mm across

What materials are the gems made from and how do they look?

The stones are cast from resin and finished with an AB-like iridescent coating that reflects light to create a multi-hued sparkle. Their faceted cuts are designed to catch light at different angles, giving projects a lively, jewel-like shimmer without the weight of glass or crystal.

• Resin construction for lightweight durability
• AB-style coating for color-shifting shine
• Precision-cut facets for consistent sparkle
• Suitable for indoor decorative use and crafts

How do I attach these non-hotfix flatback rhinestones?

Because the gems are non-hotfix, they require an adhesive for lasting placement. Use a craft-specific glue such as B7000 or E6000 for textiles and hard surfaces; nail glue or topcoat works for manicure applications. Always clean the surface first and allow full curing time as recommended by your adhesive.

• Clean surface before application for best adhesion
• Use B7000, E6000, nail glue, or craft-specific adhesives
• Place with the included tweezer or pickup pen, then let dry fully
• Test a small area for fabric flexibility and washability

What creative projects can I make with this rhinestone collection?

The large quantity and mixed colors make this set ideal for medium-to-large designs like phone-case gradients, bedazzled drinkware, or multi-piece costume work. It’s also practical for smaller accents such as nail art, hair clips, or scrapbook embellishments—mix and match shades for contrast or color-block effects.

• Bedazzle tumblers, mugs, phone cases, shoes, and bags
• Create rhinestone nails, hair accessories, and jewelry accents
• Pave sections of costumes, wedding embellishments, or frames
• Use for diamond-painting fills and large-area mosaics

Who is this for? Crafters, makers, and small-batch designers who need a high-volume, economical supply of small, colorful flatback gems will find this TINKRSTUFF set useful. It’s suited to hobbyists working on personalized gifts, party decorations, cosplay costumes, or salon-style nail art. Because the rhinestones are non-hotfix, shoppers who prefer to choose their adhesive and placement method—whether temporary or permanent—will appreciate the kit’s flexibility. Consider this box if you want a well-organized, color-diverse stash of 4mm gems with simple tools to speed up accurate application.
