I write mitlerweile for nearly 1 semester just about anything with the pins, and just for mathematical calculations and everything where you need very fast and correct a lot of the pins just great. Even overwriting off-etched points is usually no longer visible (as long as you do not just picturing surfaces and erased). In any case, you get everything destroyed almost without a trace, if you will: D
The only Mankro is not just inconsiderable price. The 0.7er mines (pen tip) have barely survived more than 2-3 weeks with me, holding 0.5 there already again one week more. Nevertheless, expensive Gschäft here on the site. For this deduction 1 star.
