WTT for Astronautic Engineering Skillbook, will give PLEX

I am looking for an Astronautic Engineering Skillbook. Ideally, I want to trade PLEX for it. I am willing to offer 10,000 PLEX.

Sale complete. 10,600 PLEX. Skill injected. Heading home.
I considered flying the skillbook home before injecting, but chickened out.
