Pilot FriXion erasable stamp | FriXion stamps use a special thermo-sensitive ink that turns invisible when rubbed with the built-in friction 'eraser' | 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 FriXion advise against using it on envelopes or leaving anything marked with FriXion ink in a hot car | Like magic ink, erased FriXion ink reappears if placed in a freezer or otherwise exposed to temperatures below -10Degree C | The erasable Pilot FriXion Stamps are a fun way to mark dates in your calendar and much more | With no damage to the paper, you can easily erase and re-stamp if plans change! | Erasable ink | Lanyard Hole |This product is sold individually.
