Magnet in heat-shrink tube coating

Small unit magnets available in round (radial magnetization) and square (thickness magnetization) shapes, offering customizable magnetic properties.

Magnetic Zipper Closure: NdFeB magnets encased in heat-shrink tubing for enhanced protection and easy handling, offering flexibility for customized closures.

Magnetic Zipper Closure encased in heat-shrink tubing, offering durability, waterproofing, and flexibility for a variety of applications.
Richarms supplies high strength hidden magnet for bag and purse pouches closures. These hidden magnet packed in long tube can be used as pocket closures. Our hidden magnet come in different strength and range in many sizes in both round and rectangular shapes.
Compared with a set of traditional magnetic snap, this magnetic closure packed in tube design offer a full seal solution as zipper does. It’s better than a zipper for it’s smart to close by attracted to the other side when the user just easy make the pouches both side closer, and the customer can be free from getting stuck.
In the above picture, magnet material is N45, size is 3mm diameter and 10mm length, diameter magnetized. Magnet size, grade and the tube length can be made as per your order.
En heat-shrink tube puede ser transparent, natural color, negroo incluso personalizado to match your specific design needs. This added customization provides enhanced aesthetic options and allows for tailored branding y functional protection.

Various heat-shrink tube options for Bar NdFeB magnets, including transparent, natural, black, and customizable colors for tailored design.
Structure Options: 3 Magnetic Zipper Closure Layouts (Choose by “Strength vs. Flexibility”)
Our magnetic zipper closure strip can be built with three internal layouts. All options use a protective outer tube (EVA/TPU/Plastic tube), while the inside core determines closing strength, flex feel, and how “forgiving” it is on curved openings.
Option A — Alternating (1 Magnet + 1 Silicone Spacer)

Magnetic zipper closure cross-section with two magnets then silicone spacer (MM–S repeat) inside a flexible tube.
Best for: softer feel, smoother bending, curved openings
Layout: M | S | M | S | M | S ...
Why buyers choose it:
- More flexible, easier to follow curves
- Softer hand-feel due to silicone spacing
- Great balance for pockets / apparel openings / sleeve edges
Typical core examples:
- Magnet: 3×6mm N35 o 3×10mm N52
- Spacer: 3×10mm silicone
- Standard OD: ~3.5mm; length 100mm / 160mm / custom
Option B — Full-Magnet (Continuous Magnets)

Magnetic Zipper Closure Structure B (Full-Magnet Core)
Best for: maximum holding force, straight openings, premium “snap-close”
Layout: M | M | M | M | M ...
Why buyers choose it:
- Strongest attraction along the entire length
- Feels most like a “magnetic zipper” when closing
- Ideal for bag openings, structured casesy clean-edge closures
Typical core examples:
- Magnet: 3×6mm N35 o 3×10mm N52
- Standard OD: ~3.5mm; length 100mm / 160mm / custom
Option C — Grouped (2 Magnets + 1 Silicone Spacer)

Magnetic Zipper Closure Structure C (M–S Alternating Core)
Best for: strong closing + extra flexibility (balanced “power & comfort”)
Layout: M | M | S | M | M | S ...
Why buyers choose it:
- Strong “closing points” from paired magnets
- Silicone gaps give better flexibility than full-magnet design
- Great for fashion goods where both hold + comfort matter
Typical core examples:
- Magnet: 3×6mm N35
- Spacer: 3×20mm silicone
- Standard OD: ~3.5mm; length 100mm / 160mm / custom
Quick Selection Guide
- Need maximum strength? → Option B (Full-Magnet)
- Need best flexibility/soft feel? → Option A (Alternating)
- Need a balanced “strong + flexible”? → Option C (Grouped)
