Since the mines are much more expensive in our little village shop, I order it on Amazon. My son writes exclusively so, because with a filler, there is only graffiti. Very nice is that you can erase the ink again and override. A pity, I find that the mines are different filled with ink. Time is more in it, sometimes less. We need on average one mine per week since the mines, no matter how much is in there, never really full.
