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!
