Description
Uni ball R:E is a smooth-writing gel pen that erases cleanly and easiy. The R:E features heat-sensitive ink that turns invisible when exposed to heat by rubbing it with the plastic friction “eraser” in the pen’s push button. The friction eraser produces no dust when used and doesn’t wear out.
A special mechanism in the push button locks it in place when the pen is turned upside down, letting you erase as hard as you want without clicking the pen.
Notes: The ink will turn invisible if exposed to temperatures over 140 Degree F (60 Degree C). We don’t recommend using it for signatures, legal documents, or addressing envelopes. We also don’t recommend leaving the pen or anything you write with it in a hot car. The ink may reappear if exposed to temperatures below 14 Degree F (-10 Degree C).
