The Felt-tip pens have bright colors and can paint on many surfaces, such as paper, cardboard, wood etc. Felt-tip pens can be recharged by applying 2 drops of lemon juice or vinegar on the color pad by opening the back cap with a pliers or dull knife. 

The specially designed tip cannot slip inside the pen or bend under pressure. Use the eraser-marker to remove the ink of the felt-tip pens from the paper, skin and many other surfaces. The eraser-marker can be used as secret inks, which only become visible after being painted over with the felt-tip pens.

Right from the very beginning, ökoNORM's philosophy remains unchanged: To produce high-quality, environmentally friendly and non-toxic products, made from sustainable resources.
