Our DIY set of hand film powder is made of model powder: talc powder, sodium alginate, calcium chloride, casting powder: calcium carbonate, calcium sulfate. Designed for making 3D hand models easily and freezing precious moments. The method of use is extremely convenient: add the molding powder and water to the bucket, and stir evenly with a mixing rod. Dip your hand into the solution and wait for 3-5 minutes. When the solution has changed color and solidified, gently shake your arm to remove it. With gloves on, add the casting stone powder and water to the other container and mix well with a mixing stick. Pour the mixture into the mold and tap the rim of the bucket to reduce air bubbles. Wait more than 30 minutes for it to set, then peel off the outer layer with a sharp stick. You can sandpaper the surface of the model to make it more beautiful. And the gap can be filled fine to improve the smoothness of the model surface.
