1. Compared to other products, ELK's piping bag uses 60HA elastic silicone, which is the perfect material for piping nozzle sets. The slight elasticity ensures its reusability and allows sticky liquids to flow smoothly inside. It won't break even if you knead thick batter. Its high elasticity means that all the squeezing efforts you make will be transferred to the raised sides when stretched, rather than squeezing the frosting out the bottom. 2. The smooth interior of the piping kit allows the frosting to come off easily after washing with warm water. It is really a good choice when you make cupcakes, cookies and breads with brightly colored frostings, and it will not cause colored residue like other cheap pastry bags. You just need to turn it over and wash it with warm soapy water. The slightly textured non-slip appearance allows you to hold it more comfortably and is also easy to use. 3. Easily switch piping mouths: The converter will not get ridged during the squeezing process, and you can easily switch the frosting bag tip without emptying the frosting or changing the piping bag. This is definitely helpful for cake decorations with different patterns. Cake decorating supplies include: 2 pastry bags and 6 stainless steel frosting tips, 2 standard converters, 2 silicone rings, 3 cake scrapers. 4. The frosting piping bag is perfect for making cupcakes, cakes, breads and cookies and other different desserts. It really helps with daily baking, professional baking, and is suitable for parties
