Why not make life easier and use disposable icing bags to save all that messy cleaning up when you're cake decorating?
These bags measure 29.5cm long and 16cm at the wide end and come on a handy tear-off roll. Simply use a scissors to trim the narrow end to the size you need and you can use them with or without a nozzle. If use them with a nozzle you may need to use a coupler depending on the size of the nozzles and what you're using it for.
