The heat-shrinkable sheet shrinks when heated. It can be made into flat ornaments or three-dimensional ornaments, such as brooches, rings, accessories, keychains, gift tags, bookmarks, and other crafts. Advantage: Made of premium material, strong enough after heat shrinking, nor easy to break. Style: You can cut it to any size according to your needs. The surface of the heat-shrinkable sheet forms a slightly frosted texture after being sanded, which helps the paint or color adhere and facilitate coloring. Instruction You could use a colored pen to draw your favorite cartoon pattern on a film. After the pattern is drawn, punch a hole and blow it with a heat-gun for 1 minute, or you could heat and shrink it in an oven. NOTE: 1. Household hair dryers cannot achieve the high temperature required to deform heat-shrinkable sheets and are not recommended for use. 2.Do not handle the shrunk heat shrink sheet directly with your hands, as you may get hurt. 3. The pattern on the heat shrinkable sheet needs to be avoided from scraping and rubbing hard to avoid color discoloration problems.
