Refill for the Rondo Erase pen with erasable ink.
The ink is heat sensitive and by that is meant that it disappears when it is heated. Using a special eraser on the pen, the paper and the ink heat up as it is erased by the friction that occurs. The ink becomes invisible but can return if the paper cools down by, for example, being placed in the freezer. The eraser is made of silicone, built into the top of the pen and is indestructible.
The ink refills are available in the colors blue, black, green and pink. When the ink runs out, the cartridge is replaced and the empty refill can be recycled as metal.
Tip: Medium
Color: Blue, Black, Green, Pink
