Good point, but I'll note that I actually use these for court stipulations (i.e. very important writing). My use case is for documents where the document will be photocopied after signed by all parties and the photocopy becomes the filed document so this alleviates the concern.

>Also, IIRC, extreme cold can bring the ink back, so I also wouldn't trust these to hide sensitive information.

Oh fun - I put an erased paper in the freezer and will report back!


Fair enough. I'll add the bit that they're fine if you don't need the ink to be anything more than short term. Excited to hear how the experiment goes!
Yep - the freezer brought the ink back! Very impressive and interesting.
