Uni-ball R:E Erasable Gel Pen Blue 0.5

• Retractable erasable gel ink ballpoint pen
• Improvement of eraser performance: uni-ball R: E's eraser is a newly developed eraser! Equipped with a knock bar lock mechanism: When erasing letters, etc., the knock bar is locked simply by turning the shaft upside down, so it can be erased firmly. An easy-to-use knock type has been realized
• Enjoy a smooth-writing gel pen that erases cleanly and easily! 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° F (60° C). The ink may reappear if exposed to temperatures below 14° F (-10° 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
