Rollerball refill for Frixion Ball 2260 and Frixion Clicker 07 (2270). Refill: BLS-FR7 Equipped with the patented, metamorphic Frixion ink. Using the plastic tip at the end of the shaft of the pen and the generated friction heat (approx. 60 °C), the writing can be rubbed away. Cold causes the reverse effect. A short time in the freezer (approx. -10°C) let the writing appear again. The lead with stainless steel tip ensures particularly high pressure resistance and durability. Ball diameter: 0.7 mm corresponds to a line width approx. 0.4mm
