If you enjoy decorating cakes. These are a must have.  It's so much easier to me to toss these bags into the garbage than to try and clean the other ones.  Especially if you just got a small area to decorate you don't even have to use a coupler and that's even less clean up. 

 Great product to have for Mother's that really don't have the extra 20 minutes to spend cleaning up the featherweight bags.
