1. Material: food grade silicone2. The groove width of the silicone pad is 1.5mm, which is universal for various 3D pen print heads. The extrusion of the mold pad is compatible with various 3D filaments and 3D pen nozzles.3. Easy to pop out, will not stick to the printing filament, just bend the flexible 3D pen drawing pad, and the dry 3D filament can be easily popped out4. High temperature resistance, can withstand high temperatures up to 230 degrees Celsius, which can prevent your table from being scorched during 3D creation5. The pen pad can be washed directly with water or washed in a dishwasher6. The silicone pad is used to etch multiple shapes of drawing graphics: rings, triangles, grids, rectangles, etc. You can use these basic shapes to form more different shapes and build three-dimensional graphics, making your 3D drawing more convenient and accurate7. Each set comes with 2 small heat-proof finger cots (for children). The finger cots can protect your fingers from hot wire and drawing.8. Size: 17.7x17.7x0.3cm, large size 41.2x20.3x2.5cm9.
