Why Choose JustKraft

JustKraft sources pin backs built for actual craft use, not just display. The locking clasp on these 30mm bar pins closes with a firm click and stays shut, which matters when you are attaching something handmade to delicate fabric. The two sewing holes are spaced wide enough to give a stable hold whether you stitch or bond them with adhesive. You get 10 pieces so you can complete a full batch of brooches without ordering again.

Pro Tips

When gluing this pin back onto a resin or clay base, use a two-part epoxy or E6000 adhesive for the strongest bond. If sewing onto fabric, use both holes with a double thread for extra stability. For saree brooches, position the clasp opening facing downward so the pin does not accidentally open when worn. Sand the base lightly before gluing for better adhesion on smooth surfaces.

Complete Your Setup

These brooch pin backs pair directly with resin molds for casting brooch shapes, air dry clay for sculpted jewellery, felt sheets for fabric brooches, and UV resin or epoxy resin for finishing. If you are making jewellery to sell, pick up JustKraft brooch bases, resin pigments, and glitter powders to complete your production kit.

Frequently Asked Questions

Q: What size brooch base works best with a 30mm pin back?
A: A 30mm pin back suits brooch bases between 30mm and 60mm in width. For larger bases above 60mm, we recommend using two pin backs placed side by side for balanced support.

Q: Can I sew this onto thick felt or fabric?
A: Yes. The two holes on the bar are sized for standard hand sewing needles. Use a strong polyester thread and sew through both holes in a cross pattern for a firm hold.

Q: Does the gold finish last?
A: The gold-plated finish is suitable for regular wear under normal conditions. Avoid prolonged contact with water, perfume, or sweat to maintain the finish longer.

Q: Is the clasp lock strong enough for heavy resin brooches?
A: Yes, the locking clasp is designed to hold medium-weight brooches securely. For very heavy pieces, we recommend reinforcing the bond between the pin back and the base with a strong adhesive in addition to sewing.

Q: Can I use this for kids' badges or school name tags?
A: Yes. The locking clasp makes it safer than open safety pins for attaching badges to school uniforms or event name tags.
