Long-term storage item. Unused item. The seal was broken for confirmation. The gusset at the bottom is just over 3 centimeters at its widest point. It's more of a small size, perhaps for a bachi (plectrum). Although it is unused, it has been stored at home. Please check the images and we appreciate your understanding. We also have it listed on other sites. It may be deleted. Thank you for your understanding. If purchases are made simultaneously, the person who purchased it earlier will be given priority. We apologize for any inconvenience. Thank you for your consideration. #Shamisen #Sangin (another name for shamisen) #Koto (Japanese harp) #Nagauta (a type of traditional music) #Koto (Japanese harp) #Classic patterns
