I thought these icing bags were great because they are disposable. I love that I don't have to wash anything other than the tip. When I'm finished icing I can just throw away. I have tried with one of my own tips and it fits great. The plastic is a strong material that will withstand the frosting process. I'm very happy with these bags and will defently buy more when I run out.
