Whoa, I didn't realize Pilot Frixion Erasable Pens were now available in the US (for a couple of years now). These are gel pens that turn transparent when exposed to heat - so you can essentially erase them with a blow dryer, iron, microwave, or even just rub it. Now I gave up using paper years ago but I do like the tactile feel of paper and using paper sizes that are much larger than an LCD screen size, so I'm giving these a go to see what I might be able to do with them on paper I can just use over and over again (charts, drawings, schematics, oh my!). #facebook
