Buying by metre rather than in fixed lengths means your closure follows your pattern, never the reverse. Across bags especially, where a seam rarely matches a standard length by chance, that spares adjustments which always show on a finished piece.
This coil carries 3 mm spiral width, tape width 2,5 cm. Its tape is made from 100 % polyester. Cut it by sharp scissors straight through tape plus coil, then thread your slider on from an open end.
Work a few firm stitches across that coil below, so your slider stops there. Its upper end disappears into whatever seam encloses your zip anyway.
What Reißverschluss spiralförmig 3 mm Hellrosa is suitable for
- Bags whose opening rarely matches a standard length.
- Garments carrying long closures, such as dresses or jackets.
- Anyone wanting several closures in one shade without buying them singly.
Frequently asked questions
Will this slider fit my zip?
What counts is spiral width rather than length. A slider built for narrow coil never runs over wider coil, nor the reverse. That width appears alongside zip yardage, or gets measured across your existing spiral.
How do I thread a slider on?
From an open end, guiding both spiral sides parallel, pushing your slider straight on. Should it tilt, twist gently rather than forcing — force bends its body, after which it never closes cleanly again.
Can I set its length myself?
Yes, which is the point of buying zip by metre: cut your spiral to measure, thread a slider on, secure both ends. Your closure then fits that bag or garment exactly, instead of the other way round.
How do I secure both ends?
Across its lower end, work a few firm stitches over that spiral, so your slider cannot run off. At its top, whatever seam encloses your zip takes over that job.
