I for years used the 3C business cards around for specific needs low even to print business cards. I find much more practical and not least much cheaper than 500 or 1000 same business card somewhere to be ordered to only to a few months later might be able to throw away 50-80% of it because some small detail has changed. Because I'd rather have each a few dozen, according to occasion cards: private, for the company or if you are working as a self-employed in several business segments, each matching.
Have you already run by various laser printers and there were never any problems. Just let it cool down and then detach from the paper. Or rather solve The paper of the cards so that they do not bend unnecessarily in this procedure. It takes maybe 10-20 seconds per sheet with 10 cards, less if you have fast fingers :)
The only downside: It takes usually not long before the rest of the family knocks on whether one could not even for a few print ...
