Teflon Washers TT 0365-05 x 6 pieces Since these are mass-produced items, image ① is reused. Please use them to reduce stiffness during tuning work. ※ Musical instruments are not included. Used on a Spirit (image ②, example of use) It's a classic, but it's become a little easier to turn. ※ I'm using washers from a manufacturer that seemed good based on research online, etc. These are not "specialized products" from a guitar parts manufacturer. Please note that this is just a reference, as there may be individual differences in instruments. I don't think there will be any problems, but it hasn't been confirmed whether they can be used on all other Steinberger series. 【Shipping】 They will be placed in a plastic bag like image ③ and shipped via anonymous delivery to your mailbox. Although they are new, there may be minor scratches or dimensional differences.
