Genuine Schaller peg buttons, small size, set of 6. Made of ebony for guitars. Fits Schaller M6 series tuners. Sold at a certain store for 6,040 yen. https://www.soundhouse.co.jp/products/detail/item/67670/ I bought these but they didn't fit my equipment, so I've been storing them at home. They've only been installed a few times and are practically unused. The bag doesn't have the manufacturer's name on it, but they are definitely genuine products. Six flathead screws for installation are included.
