Pilot FriXion Erasable Gel Ink Pen - 0.5 mm - 8 Color Set LFB-160EF-8C

8 color set includes: black, purple, blue, light blue, green, orange, red and pink. A breakthrough in writing technology has made available the erasable pen you have always been waiting for. These new pens from Pilot erase by FRICTION, they are like a magic pen for adults! The pens have a special rubber end to rub the thermo sensitive ink away with, thus no eraser by-products are produced, yet the ink disappears magnificently (and the rubber never wears out!) The pen writes smoothly, in vibrant colors, and erases without a trace! Best of all, they are made of 76% recycled plastic. 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 thermo 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 friction.
