If you don't have a nozzle attachment, it's still possible to attach a tip (nozzle) to the cream bag. Here are the simple steps: Prepare the piping bag: Cut the tip of your disposable or washable bag with scissors to match the diameter of the nozzle you will use. Be careful not to cut too wide. Insert the Duyuyu into the bag: Push the Duyuyu down through the bag, positioning it so that the cut end protrudes outwards. The tip should stick out of the bag, not back out. Fill the cream: add the cream from the top of the bag. Make sure the ear is stable. Start using: You can squeeze out the cream by applying light pressure. If the sense is steady, there is no need for an extra apparatus. 💡 Tip: if you cut the bag end too wide, the sense will not stand. If necessary, you can secure it by wrapping stretch film around the object.
