Buttons

Our button families, one factory

Shirt, Blouse & Polo Buttons

The tone that matched on the sample board looks flat against the finished shirt We test it before bulk.

Faux Horn Buttons

Two production runs, two shades of 'brown horn' We test it before bulk.

Imitation Shell Buttons

The coating lifts at the rim and the customer sees a white edge on a dark shirt. We test it before bulk.

GRS Recycled Buttons

The brand's auditor asks for a transaction certificate and the supplier cannot produce one We test it before bulk.

Beads Collection Buttons

A decorative bead detaches and fails the small-parts test We test it before bulk.

UV & Digital Printing Buttons

A printed logo rubs away and the brand treats it as a quality defect. We test it before bulk.

What a spec sheet never shows

Eleven testing machines. A batch number on every bag. The factory address is our registered address.

Most suppliers send a certificate PDF. We send the test result for the lot you are buying, and we can tell you which machine produced it.

  • 02Wash & rub fastness — tested to the care label you actually print.
  • 03Pull & attachment strength — the number your brand's lab will ask for.
  • 04Colour — spectrophotometer against the approved dip, kept on file for repeats.
  • 05Batch retention — a physical sample of every lot retained, so a claim can be traced, not argued.

Buttons are what we do deepest. The rest of the trims ship with them.

Zippers

Metal, nylon and moulded, tape dyed to your reference.

Drawcords & webbing

Hood cords, elastic, woven webbing — with matched locks.

Labels

Woven main labels, care labels, leather and PU patches.

Metal parts

Snaps, rivets, eyelets, buckles — plating chosen for the wash.

One PO, one shipment, one accountability. Your trim list arrives complete, on one delivery date, from one supplier who answers for all of it.

How we work

From your spec to a repeatable lot

Send the spec

Size, colour reference, care label, destination market. A photo of the garment helps more than a drawing.

Sample & approve

Physical sample with the test result for that sample. You approve a physical reference, not a screen.

Pre-production

Colour dip and material confirmed in writing. No bulk starts on an email assumption.

Bulk & record

Batch-coded bags, retained samples, and the documents your buyer's lab will ask for.

Send us the garment. We will send back the trims list.

Tell us what you are making and the market you sell into. You get a trim package with specifications, test references and one price — not five suppliers to chase.
