PILOT Frixion Ball Knock Retractable Gel Ink Pen,

The long awaited retractable version of the popular Pilot FriXion line is here! Pen features the same beloved thermos-sensitive ink that can be erased by friction, but now comes in a sleek, retractable body. Just push the clip to extend and retract the tip. A subtle yellow color appears along the barrel side to show when the pen is extended. The special rubber tip at the end allows you to erase conveniently without having to cap or uncap your pen. The pen writes smoothly and erases without a trace! Refills available for select ink colors and point sizes only. Interestingly enough, the ink in these pens will actually reappear when the temperature reaches below - 10 C (under 14 Fahrenheit). A freezer is sufficiently cold enough to make the ink start to reappear. It is like a magic pen for adults! Because the ink in this pen is thermos sensitive, we do not advise for it to be left in hot cars, used for mailing, or subjected to a condition that exposes it to a lot of fruition. Special gel ink allows to erase your writing by frixion with pen tail Erase and rewrite any number of times without damage on papers 10-color set of black, red, blue, blue black, green, light green, orange, pink, light blue, and violet Ballpoint Size : 0.5mm Not recommended for use on legal or official documents
