Mandala Crafts 13-Inch Black Nylon Zippers, 80-Pack, Closed-End #3 Coil

What to know

The 13-inch closed-end design gives each zipper a set length for sewing projects that need a fixed bottom closure, such as a pouch, pillow cover, or clothing repair. This Mandala Crafts pack includes 80 black nylon-coil zippers with metal sliders and black tape, so it suits repeat projects or keeping matching closures on hand.

Each zipper is listed as size #3, with 4mm teeth. The coil is 13 inches long, while the tape is 14 inches long and 1 inch wide. The product is described as washable and dryable, and the zippers are intended for hand or machine sewing. That makes them a practical supply for everyday fabric work, rather than a specialty closure for a project that needs a separating zipper.

How to use it

Sew the tape into a seam or opening using a hand needle or sewing machine. The listed material compatibility includes cotton, leather, fleece, canvas, denim, and vinyl, choose based on the fabric and construction of the item you are making. For example, a 13-inch zipper can close a small bag or replace a fixed zipper in a garment, while the black tape offers a simple match for darker materials. The pack is also suitable for repeated makes where using the same zipper size and color matters.

Because these are closed-end zippers, the two sides stay joined at the bottom. They are not the right format for an opening that needs to separate fully, such as some jacket fronts. Compared with buying individual closures as each project comes up, an 80-piece pack makes more sense for ongoing sewing or craft work, provided black is the color you need.

Best use cases

Consider this set for bags, pouches, wallets, cushion covers, clothing repairs, and other projects with a fixed zipper opening. The nylon coil and stated fabric range give it flexibility across common sewing materials, while the uniform black finish works well when a low-key closure is preferable to a contrasting accent. It may also be useful for a small sewing business or craft workspace that goes through similar closures regularly.

Buyer feedback is not entirely consistent on performance. Some describe the zippers as easy to sew and smooth to operate, while others report fraying or difficulty opening and closing them. That mixed feedback is worth weighing if the closure will see frequent use. A solid pick if you need a bulk supply of black, fixed-length zippers for fabric projects, better avoided if the design requires a separating zipper or a different color.

Before you decide

Are these separating zippers? No. They are described as non-separating, with both sides joined at the bottom.

Can they be sewn by hand or machine? The product information lists both methods, and names cotton, leather, fleece, canvas, denim, and vinyl among compatible materials.

Can the zippers be washed? They are described as washable and dryable. Buyer feedback on durability and smooth operation is mixed, so take that into account for items that will be used often.

Is it worth it?

This pack is most useful when you expect to make several projects that call for the same black, 13-inch closed-end zipper. Its 80-piece quantity and stated hand- and machine-sewing use give it a clear role as a craft or repair supply, rather than a one-off replacement. If you only need one zipper, want a separating closure, or need consistent performance for heavy everyday use, a smaller or more specifically matched option may be a better fit.
