Good quality open-end zips for dressmaking, crafts and home furnishings. These are open end zips (ie they separate into 2 pieces when unzipped) which are suitable for coats, jackets, hoodies, fleeces etc. They are No 5 weight (a bit thicker and more robust than standard dressmaking zips), making them suitable for heavier fabrics. The second photo shows one of these zips (cerise) together with a standard dressmaking zip (turquoise), so that you can compare them. The metric sizes are accurate and the approx size in inches is also stated.  It is also very easy to convert these into a closed end zip when you want a heavier zip e.g for a bag or notebook cover - simply buy a longer length than you need and then cut the bottom off with pinking shears once you've sewn it in place (remembering to do it up first so you don't cut the puller off!).
