This pen is definitely not suitable for tablets. I had tested it on a corner, let it be wiped off after one minute, so I happily written it happening. 2 days later I wanted to wipe the entire back, which was not possible, I had to resort to using nail polish remover again to my table. So definitely not recommended.
In addition, the first pump, the tip is already quite affected, so you also can not so super nice write, all in all, not a good buy :(
