I used these when I took the 1st and 2nd class architect exams, and since I passed, I no longer need them, so I'm selling them. I used them for two years, but only for the drafting period, so I think it was about 4 months total. This is a set sale including drafting tools, so separate sales are not possible. It's an A2-size drafting board. I think this is a lucky item, as I passed both the 1st and 2nd class architect exams without failing!
