This is a set of 5 pairs (10 sticks) of Sato Mallet's yarn-less mallet heads only. The breakdown is: 2 hard B heads, 4 medium-hard B heads, 2 medium A heads, and 2 medium C heads. The weights of each are as follows: B Head Hard: 21.2g, 23.2g B Head Medium Hard: 21.8g, 20.7g, 21.6g, 23.7g A Head Medium: 23.4g, 23.4g* C Head Medium: 26.6g, 26.4g* The older ones are about 15 years old, so there are scratches on the shaft. Images of the two most noticeable ones are included. The mallet logos were mostly stickers, so they have peeled off. *I understand that the heads with flat tips and bases are A, and the ones with indentations are C, but the names might be reversed. New retail price: 8,800 yen/pair
