[Sales End Date: Tuesday, June 30] TV Anime "Dr. STONE" x KARATZ Jewelry Store Collaboration: Gemologist's Logo Loupe & Strap Set (with explanation card)
TV anime "Dr. STONE" and jewelry specialty store KARATZ have collaborated to produce a jeweler's loupe and strap set with the KARATZ logo (with an explanation card).
This set uses a 10x loupe, which is standard for gemstone appraisal, and is designed with an emphasis on magnification and visibility suitable for detailed observation, based on the standards actually used by the jewelry specialty store KARATZ. It allows for clear confirmation of the internal structure of minerals and gemstones, inclusions, and more.
In addition to the original design with the logo, it comes with a strap for easy portability, making it suitable for a wide range of uses, from daily use to collection purposes.
Furthermore, the included explanation card provides basic instructions on how to use the loupe and observation tips.
It is designed to be easy for first-time users, allowing you to experience the "enjoyment of science" theme of the TV anime "Dr. STONE" firsthand.
