"Modoran Karakui" is an innovative product designed to simplify the tuning of the sanshin, which can be difficult for beginners. Once installed, you can tune the instrument with one hand, and the strings won't unwind. Urumaya, a sanshin shop in Okinawa, has been offering an installation service for this product to its customers. Now, they are selling it as a DIY kit, allowing you to install it yourself. The kit includes three karakui (tuning pegs), several pre-attached parts, and an installation manual. No tools are required, and the work isn't particularly difficult. However, since you'll be attaching small parts, it's not recommended for those who are not comfortable with DIY or crafts. Thank you for your understanding. *Please note that these are spindle-shaped karakui, which are slightly different in shape from the standard conical karakui. The first photo shows the karakui you will receive. Please be aware that they are not the shape shown in the second and subsequent photos. (Contents) 3 sets each: ・Modoran Karakui ・Washers ・Springs ・Nuts ・Instruction Manual (Items you will need) None in particular. A small amount of wood glue.
