Designed with bottle caps in mind, these 1/4" x 1/10" N42 neodymium magnets are a perfect fit for turning standard caps into strong, reliable fridge or board magnets. The slightly thicker 1/10" profile gives them more holding power than ultra-thin discs, while the 1/4" diameter fits neatly inside most bottle caps without extra bulk.

Made from N42 grade rare earth neodymium, they provide a dependable, consistent hold that’s ideal for crafts, DIY projects, and everyday use. Whether you’re creating custom magnets, organizing your space, or working on small builds, these magnets offer the right balance of strength and control. Each piece features a smooth nickel coating for durability and a clean finish.

Common Uses:

  • Turning bottle caps into custom fridge magnets
  • DIY crafts, gifts, and creative projects
  • Holding notes, photos, and reminders
  • Magnetic closures for small items
  • Organizing lightweight tools or materials
  • Classroom, office, or home use

Bottle-Cap Magnets and Thumbtacks

A homey take on the traditional locket, bottle caps inset with small black-and-white pictures, right, can be used as thumbtacks or magnets. Clear resin is poured into the caps to seal the photos and give them an appealing glossy finish.

Twist-off caps are better than conventional ones because they don't bend when removed. For appropriately small images, try cutting details from large photos. Or, if your software has a contact-sheet mode, use it to reduce pictures drastically.

Magnets and Thumbtacks How-To
1. Using the craft punch, cut out pictures. Using craft glue, attach one picture to the inside of each bottle cap. Let dry.

2. Cover a work surface to protect it from spills, and lay caps on top. Following manufacturer's instructions for clear casting resin, fill each bottle cap to the rim. Let dry overnight.

3. Using contact cement, attach magnets or thumbtacks to the backs of the bottle caps. Let dry overnight before using.
