・ Reference books for Japan Cosmetics Certification Level 2 & 3 ・ Reference book for Japan Cosmetics Certification Level 1 ・ Practice questions for Japan Cosmetics Certification Level 1 This is a set of 3 books. The Level 1 reference book has a few pages with pencil markings (minimal). The practice questions book also has markings (more). I apologize if I missed anything. I believe they can be used without any problems for studying. Please purchase only if you understand. (I was able to pass Level 1 on the first try!) Thank you for looking.
