Bests & Worsts Reviews from Amazon

These pens write great and being erasable is why I used them. However, the ink disappears if your paper gets too hot. As in, I live in Texas and my notes disappear in the summer. I can't keep putting my notes in the freezer so the words reappear. That's what Pilot told me to do when I asked what was going on. These pens will not be an option for me for my book writing and assignments. I am not rewriting my notes using a better pen. So, if what you write isn't important or you will keep your writings indoors, these are great for you. If you like to write while outside, in the heat, or your writings ever need to be in a hot car, then pick another pen or have a freezer handy. I would like a refund.
