• Pilot Frixion Point 04 Gel Pen Refill 0.4mm BLS-FRP4- 1pc • Model: BLS-FRP4 • 0.4mm • Ink refill for Pilot Frixion Point 04 Gel Pen 0.4mm LF-22P4. • Precise 0.4mm needle-tip point. • Its special thermo-sensitive ink turns invisible when exposed to friction by rubbing it with the special "eraser" built into the end of the pen barrel. • The ink disappears cleanly without using up the eraser or creating any dust or smearing. • The ink will also disappear if exposed to other sources of heat or friction, so we advise against using these pens to address envelopes or leaving anything written with them in a hot car. Interestingly though, erased Frixion ink reappears if exposed to temperatures below 14° F (-10° C), like if it is placed in a freezer.
