6pcs popcorn expansion pen, hot start, three-dimensional protrusion, bright colors, suitable for multiple papers, easy to operate, portable drawing pe

Our popcorn expansion pen is made of acrylate thermal expansion lotion, water-based color paste, glycerin and other ingredients. Specially designed for manual DIY creation and classroom art practice, it can enrich the expression forms of images and adapt to various paper carriers such as cardboard and sketch paper for graffiti creation. The usage method is extremely convenient: first use this product to draw patterns, then use your own hair dryer to blow hot air about 20 centimeters away from the pigment for 3-5 minutes. Then quickly approach about 1 centimeter and continue heating for a few seconds to produce a three-dimensional explosion effect. After use, the ink output is smooth and even, and the lines are evenly drawn without easy ink breakage. The flat pattern can be transformed into a three-dimensional 3D raised texture when heated. The ink layer is firmly formed, and the formed raised coating is not easy to fall off. The colors are bright and rich, which can increase the visual hierarchy and bring users a rich and interesting handmade creation experience. Packaging 1pcs
