PROFESSIONAL SILICONE PASTRY BAG: Compared to other piping bags, the piping bag uses 60HA elastic silicone, which is the perfect material for piping tip sets. The slight elasticity ensures its reusability, allowing viscous liquids to flow smoothly inside. Even if you use it to knead thick batter, it will not burst. Its high elasticity means that all the squeezing you do will transfer to the bulging sides as it stretches, rather than squeezing the icing out of the bottom. Say goodbye to colored residue: The inside of the piping set is smooth and the frosting comes off easily after being washed with warm water. It's really a great choice when you're making cupcakes, cookies, and breads with bright frosting that doesn't create the colorful residue that other cheap pastry bags do. All you have to do is turn it inside out and wash it with warm, soapy water. The lightly textured non-slip exterior makes it more comfortable to hold and easy to use. EASY-Switching Piping Tip: The converter won't fall out by the edges during extrusion, and the icing bag tip can be easily switched without hollowing out icing or changing piping bags. This will definitely help with different patterned cake decorations. Cake decorating supplies include: 2 pastry bags and 6 stainless steel frosting tips, 2 standard converters, 2 silicone rings, 3 cake scrapers. BAKE LIKE A PRO: Frosting piping bags are perfect for making cupcakes, cakes, breads and cookies, and other different desserts. Very helpful for daily baking, professional baking, party gatherings. Imagine others complimenting you on the appetizing appearance of your cakes and desserts.
