This is some seriously good work from all those involved. Although I may have no (immediate) need for them I'll forward the news to some guys who might be interested. Had great service from you, Markus, on my first order which won't be the last!
However, are these flags the misprinted one you mentioned on the blog? 'cause I'm pretty sure that's no "k" but a "tz", and it looks like the font used here couldn't produce an "ä". I'm sure you've addressed that already, so just curious.
PS: Congrats for passing the exams. Always a relief.
