0.71 in / 18 mm 28L Sew-On Magnetic Snap for Handbags and Purses – No Press Required SB 10132DIK

A Sew-On Magnetic Closure for Bag Makers

This 0.71 in / 18 mm magnetic snap is made for sewists, leathercrafters, purse makers and small brands that want a practical magnetic closure without investing in a press or setting dies.

The socket and stud components feature sewing holes around their outer edges. Position the components on opposite sides of the opening, stitch them securely and test the alignment. The result is a functional closure suitable for handbags, wallets, clutches, notebook covers and textile accessories.

Because the snap is sewn rather than mechanically pressed, it works well for prototypes, one-off designs, repairs, craft markets and small-batch production. It can also be removed and replaced by carefully opening the stitches.

Why US Bag Makers Choose a Sew-On Snap

• No hand press or industrial machine is required.
• Installs with common sewing tools.
• Useful for small-batch Etsy-style production and craft-market inventory.
• Helps reduce startup equipment costs.
• Can be replaced without permanently altering the project.
• Works in compact areas where a press cannot reach.
• Can be visible or concealed under a compatible lining.

• Gold: Coordinates with gold-tone purse chains, clasps and zipper hardware.

Minor shade differences may occur because of lighting, monitor settings and production batches.

How to Install

1. Mark the points where the socket and stud should meet.
2. Check that the magnetic faces are oriented correctly.
3. Select a needle and strong thread suitable for the project material.
4. Sew each component through its perimeter holes using even stitches.
5. Secure the thread on the reverse side of the material.
6. Open and close the project several times to verify alignment and stitch strength.

Using the Snap Under a Lining

The closure may be sewn on top of the lining for a visible hardware detail or concealed beneath a compatible lining for a cleaner exterior.

Fabric between the magnets can reduce holding strength. Always test the actual outer fabric, interfacing, foam and lining together. Thick or padded constructions may prevent the snap from closing as expected.

• Handbags and shoulder bags
• Purses, wallets and clutches
