This is the Akahon series for clinical laboratory technicians. I bought it at school, but I barely used it, so it's been in my possession. As far as I can tell, there are no markings. The cover is sun-faded, but the inside is clean and in good condition. I'll offer a small discount if you purchase it as a set with other Akahon series books. Please let me know in the comments.
