Weaver Leather #5 YKK Zipper - Complete, Black, Solid Brass, 6 Inch Review (2026)

A complete, ready to sew zipper

This is a complete zipper assembly rather than a bulk chain sold by the yard, meaning it arrives with the slider already installed and the top and bottom stops in place, ready to trim to length and sew directly into a project. Weaver Leather sells this as a #5 YKK zipper, referring to the width and pitch of the zipper teeth, in black tape with solid brass hardware, and a finished length of 6 inches. Because the slider and stops are pre installed, makers do not need to separately source and attach a slider or crimp stops onto raw zipper tape, which is a meaningful convenience for anyone who does not already have a zipper assembly setup.

YKK teeth and brass hardware

YKK is one of the most established zipper manufacturers used across the leather goods and bag making industry, known for consistent tooth spacing and reliable slider action, which is part of why Weaver Leather sources this component from them rather than an unbranded supplier. The solid brass construction of the teeth and slider gives the hardware a warm gold tone that reads as classic and durable against black, brown or tan leather, and brass generally resists corrosion well compared to some plated alternatives. A number 5 sized zipper is a mid weight option, sturdy enough for pouches, small cases and bag closures without being as heavy or bulky as a number 8 or 10 zipper meant for larger luggage or heavy duty gear.

Sizing for pouches and small bags

At 6 inches finished length, this zipper is sized for smaller projects such as coin pouches, small zip pouches, pencil cases, and closures on compact accessories rather than full size totes or larger bags, which typically need much longer zipper runs. Makers working on larger bags should look at Weaver's longer lengths or their zipper by the yard option, which allows cutting a custom length and attaching sliders and stops separately for projects that need more than a few inches. For anyone building a line of small leather goods in a consistent size, ordering the exact 6 inch length needed avoids extra trimming and waste compared to buying long zipper by the yard for a short project.

Buying one at a time versus in bulk

This listing is sold as a single complete zipper, which is convenient for a one off project or for testing a color and hardware combination before committing to a larger order, but the per unit cost adds up quickly for anyone making multiples of the same pouch or case. Weaver Leather also sells this zipper style through its own supply site in various lengths and, separately, offers zipper by the yard with hardware sold individually for makers who want to assemble their own custom lengths at a lower cost per unit when working in volume. Buyers planning a production run of several identical pouches should compare the cost of ordering multiple complete zippers against buying zipper tape and hardware separately in bulk.

Who this zipper suits

This complete 6 inch zipper is a good fit for makers building small pouches, cases or accessory closures who want a ready to sew component from an established brand without assembling their own zipper from tape and separate hardware. The solid brass, black tape combination pairs well with most leather colors and gives a finished look without extra shopping for matching sliders or stops. Buyers who need a longer zipper for a bag, who are working in a hardware finish other than brass, or who are producing enough units that buying by the yard would be more economical, should look at Weaver's broader zipper range rather than this single fixed length listing.
