This is a set of two books for the "Service Etiquette Certification Level 3" exam. Service Etiquette Certification Exam Guide Level 3 [Revised Edition] (Price: 1,000 yen + tax) Service Etiquette Certification Actual Question Collection Level 3 (23rd to 27th Exams) (Price: 1,200 yen + tax) ■ About the Condition of the Product: I purchased these for exam preparation, but I never used them and have been storing them at home. There are no writings or signs of opening inside, and they are in very clean condition. ※ Important Notes: Although these are unused, there is a **slight stain (dot-like mark)** on the side, which appears to have occurred during storage (see photo 4). It is not very noticeable at a glance, but please refrain from purchasing if you are looking for a perfect new item. ■ About Shipping: I will put them in a waterproof vinyl bag and carefully pack them for shipping. The content is very helpful for job interviews and improving customer service skills. Immediate purchase is OK! Thank you. Shipping may be changed from "Rakuraku Mercari Delivery (Nekopos)" to "Yuyu Mercari Delivery (Yuu-packet)". **Please be aware of this beforehand.** Thank you for viewing. #ServiceEtiquetteCertification #Level3 #BusinessCertification #JobHunting #ReferenceBook #CustomerServiceManners #QuestionCollection #WasedaEducationPublishing
