Ever read a review after you get the shipping confirmation? Yeah, sorry if that happened to you too. The bags aren’t labelled. No big deal: put each bag under the microscope/magnifying glass, find one facing up, read the number, check the on-line datasheet, write the number in one of two colo(u)rs of pen depending on PNP or NPN. Now you’re set for the next time you need to figure out how a transistor works again after a few decades away. That might not be a problem for you.
