This piping tip can be used with a wide range of piping bags including parchment paper, disposable piping bags and fabric bags, in addition to most adaptors, couplers and icing guns. This is a larger piping tip, best used with a 14" piping bag (or larger). When using your stainless steel piping nozzles simply cut your piping bag to the size required and pop your nozzle into the bag. If you want to change your tips with ease then simply attach a coupler to your piping bag. This will allow you to change your nozzle without having to change your icing bag. This stainless steel piping nozzle is made in Korea, so you are guaranteed a high quality product that will last a life time if looked after correctly. For cleaning your nozzles we recommend that you use a piping tip cleaner brush. Size:approx 24mm diameter at bag endapprox 40mm long
