15cm Invisible Zippers YKK

15cm Invisible Zippers YKK

A 15cm invisible zipper is the short, hidden closure you reach for when a regular zipper would add too much bulk to a small opening. The teeth stay tucked behind the tape, so once it's sewn in, all you see is a clean seam line with a small pull tab. This category is made up of YKK zippers in this compact length, non-divisible, which means both sides stay joined at the bottom, exactly what you need for cushion covers, pouches and other closures that don't need to separate completely.

These zippers come from Japan and are built with polyacetal plastic teeth in a fine size 2, set on a polyester tape 22mm wide. The slider locks automatically once you stop pulling, so it won't creep open on its own while you're working or wearing the finished piece.

What makes an invisible zipper different

Where an ordinary zipper leaves a visible row of teeth running down the front of a garment, an invisible zipper hides that row on the back of the tape. You insert it with the teeth folded toward the wrong side, stitch close to the fold, and the result is a seam that looks continuous from the outside. Only the slider pull remains visible, usually sitting flush with the fabric once the zipper is closed. That's what makes this type a common choice for dresses, skirts and trousers where a visible closure would interrupt the line of the garment.

Technical specifications

Every 15cm zipper in this range shares the same build: a non-divisible invisible zipper with size 2 teeth in polyacetal plastic, mounted on a 100% polyester tape of 22mm wide. The tooth width measures 3mm, which keeps the closure fine enough to disappear into lightweight and mid-weight fabrics without adding stiffness to the seam. Because the length is fixed at 15cm, there's no need to shorten or cut these down for most small applications, though you can still trim the tape above the stop if a project calls for it.

Where you'll use a 15cm length

At this short length, the zipper suits closures where space is limited rather than garments that need a long opening. Based on the applications these zippers are made for, you'll find them useful for:

• Cushion covers and home decoration pieces where you want a neat, hidden closing edge
• The back or side seam of fitted dresses and skirts, particularly on smaller sizes or children's wear
• Trouser waistbands and other small fastenings on garments
• Pouches, small bags and similar sewing projects that need a discreet opening

If your project needs more room, such as a full-length dress zipper, the 22cm Invisible Zippers YKK or 25cm Invisible Zippers YKK will sit better along a longer seam, while the 40cm Invisible Zippers YKK and 60cm Invisible Zippers YKK cover larger home decoration items like cushion inserts or long garment seams.

Colour range in this length

This 15cm range comes in a set of practical, everyday colours: black, white, beige, navy and ecru. Black and navy work well on darker garments where you want the closure to truly vanish, while white, beige and ecru are suited to lighter fabrics, linen work, and pieces where a pale thread colour and zipper tape need to match the base cloth. All five share the same construction, so the choice comes down to which shade blends with your fabric.

Ordering and availability

Each zipper in this range is sold per piece, so you can order exactly the number you need for a single project or stock up for multiple garments at once.
