Large Greaseproof Reusable Piping and Icing Bag 5 "Best icing bags!" Mercedes 04 May 2012 I have a number of these in various sizes and find them to be the best I've had!! They are easy to grip - not too slippy, and are just perfect. Pop them in the dishwasher and come out just like new. They are a little expensive, but worth every penny - would recommend.
