felt-tip pen 9+1, 9 colors + 1 eraser-pen

The Felt-tip pens have bright colors and can paint on many surfaces, such as paper, cardboard, wood etc. Feature water-based inks with a faint odor. The dry-out rate is approx 5 % per month. Felt-tip pens can be recharged by applying 2 drops of lemon juice or vinegar on the color pad. Therefore you must open 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.
