Brand positioning and origin

TOYO Fastener is a Japanese metal zipper brand operating under Toyo Industry. Its catalogue is deliberately concentrated on metal constructions, with an emphasis on the tooth and slider tolerances that determine how a heavy zipper feels in the hand and how it behaves after thousands of cycles.

Japanese metal zipper production is characterised by tight control of stamping, polishing and plating, and TOYO follows that pattern. The result is a tooth line with consistent height and spacing, a slider that engages without forcing, and finishes that hold their appearance on exposed applications such as jacket fronts, bag openings and leather goods.

Product range

The offer is metal-centred, with a small supporting range:

  • Brass zippers in #3, #5, #8 and #10, in standard and Y-tooth profiles.
  • Aluminium zippers for lighter weight and for anodised colour effects.
  • Nickel, antique brass, black oxide and painted finishes for design-led applications.
  • Open-end, closed-end and two-way configurations for jackets, bags and separates.
  • Custom pulls, engraved sliders and leather pull tabs on a made-to-order basis.

Typical applications

TOYO articles appear mainly on products where the zipper is visible and handled often: leather jackets and biker styles, denim and heavy twill trousers, premium bags and briefcases, wallets and small leather goods, and workwear. Aluminium versions are used on lightweight jackets and on designs where a coloured metal finish is part of the look.

Quality and compliance

Metal zippers are checked for tooth pull-off, slider locking, crosswise strength and salt-spray corrosion resistance, following methods such as ASTM D2061 and BS 3084. Plated parts can be supplied with nickel-release test data, and OEKO-TEX Standard 100 articles are available. Certification for a specific article is subject to the supplier's certificates.

Sourcing notes

As a specialist metal house, TOYO has narrower distribution than the large Japanese groups and is usually bought through agents or direct factory orders. Minimum order quantities are moderate and are quoted per article, finish and length. Custom pulls and new finishes require tooling, with sampling around two to three weeks. Bulk production generally runs four to six weeks depending on finishing.
