Uniball's "thermal erase ink" has the property of becoming colorless when applying heat of 60 ℃ or more. Since chemical change occurs due to frictional heat generated by rubbing the drawn line with a special eraser of the knock part, the ink becomes colorless, so it can be erased and rewritten many times.
When writing, you can knock smoothly by turning the pen tip down like a general knocking type ballpoint pen. When needing to erase, just by turning the shaft upside down, the built-in "locking mechanism" operates and you can erase it firmly with the eraser.
Please note: Some colors may no longer be available.
Available in .38mm and .5 mm
Choose from 8 colors: Off-black, Cobalt Blue, Rose Red, Violet, Green, Sun Orange, Cherry Pink, and Sky Blue.
Rewrite over the same spot again and again - no wasting paper and creating messes!
