I'm an engineering student tired of wasting tons of paper studying and I discovered this notebook one week ago and I immediately bought it. The notebook is amazing, it works perfectly, with some hot air the ink disappears but reappears after some minutes (i think it is due to the low winter temperature) but with some water and the cloth provided everything is fine. I received also two pens - the old version I was told - and they stopped working after some days so I contacted the support and we find a solution in a couple of hours! 1000% satisfied I think I'll buy another notebook in a couple of weeks!
exactly as described, works great, nifty ideas. you can write on the paper and then erase it and reuse. the paper is not regular paper it has a gloss finish on it which allows for you to erase the ink with the pen provided. you must use the pen provided as it is a special erasable ink. recommended this product and the seller.
What a nice book is this, must be magic! See the attached photo's for a reference. Do not know how long the ink will be erasable for, and only tested the ink with a wet wipe. Either way, the app workt very good as well, no problems detected so far and the images (PDF or other files) shares easily with other programs and apps. I'll order a few more for the office and to give away for presents!
