This is a set of PRESTINI pads, the remaining individual pads that couldn't be assembled into a set of the same sizes and quantities as the genuine Yamaha flute pad set [PAD SET YFL-411H (THIN PAPER) Part No.: L0190005] used in my daily work. These are leftovers from a large purchase of pads made when I went to the United States to train in wind instrument repair in my younger days. The printing on the back of the backing card was in a transitional period at the time of purchase, and I was able to buy a large quantity because they were okay even though they weren't Hermes by PRESTINI. I found these while cleaning out the instrument storage room, as ordered by my family. For those who need them, please. 【Pad Sizes】 The outer diameter of the pads has been measured using a digital caliper. The outer diameter tolerance is set to minus, so they should fit unless the cup is extremely distorted. ・16.3 mm × 47 pcs ・17.7 mm × 207 pcs ・19.4 mm × 220 pcs Total pads: 474 pcs
