(Can be used repeatedly) Can be used for drawing, doodling, and studying. Great for a wide range of occasions such as meetings, paper presentations, office bulletin boards, DIY and everyday updates. Easy Installation: You can cut the size you want and clean smooth surfaces such as wood, glass, tile, etc., with a cloth and then stick it on and use it immediately. Of course, to save space, you can put it on the ground only when using it. (Easy to Clean) Use a wet towel or eraser to wipe it clean and reuse it repeatedly. This is an adhesive type so you can simply peel it off and stick it on without glue. There is also a scale on the back, so you can easily cut it to your desired size with a pair of scissors. Safe Material: Eco PVC material (non-toxic, safe, safe, safe and removable) Large size: 17.7 x 78.7 inches (45 x 200 cm); Color: Black; Note: Compatible walls: Paints, wood products, plaster, etc., may peel off the wall material when removing it. Fusuma and paper wallpaper may also be peeled off. Cannot be used on textured surfaces such as dirt walls and sand walls, or surfaces containing fibers such as fabric, and delicate materials such as Japanese paper from shoji shimi. Installation Instructions: 1. Fold the back of the black boat sheet about 2.0 inches (5 cm) (or cut). Apply to the edge of the surface (cling), so that it does not warp. 2. Peel off the backing paper 2.0 to 3.9 inches (5 to 10 cm). If that happens, hold the end of the backing paper and peel off the surface of the label so that it is stuck to the pin. 3. Stick the surface with a soft cloth, etc., while pushing the air to the edge of the arrow. Repeat each of the pieces between the 2nd and 3. 5. If there is a place where the final air is entered, press the part and squeeze the air out. 6. Finally, tightly and evenly close the entire surface. Easily cut to your desired size with scissors or cutter! Enjoy crafting with your children.
