I’ve used these before and they’re super easy to use and throw away without having a huge mess. For the price, they’re cheap enough to buy and not worry about wasting them. I put my tip in one bag, and put the icing in another. Then I can add to the bag with the top in it once the inside bag is empty with icing. It makes it easier to clean up and remove the tips. Try it it works, and they’re so thin that the extra is not to much thickness that it effects you squeezing it as you apply the icing. Hope this tip helps! I got it from a good friend, and after seeing her use them this way I thought how genius!
