These are press-in saddles for the synchronized tremolo unit found on Fender guitars, including the Stratocaster. They are parts that are prone to getting dirty and rusting. How about these as replacement parts? 【Specifications】 ■ Material: Steel ■ Color: Chrome ■ Body Size: See image ■ Weight: Approximately 25g (set of 6 saddles) ■ Included: Hex wrench x 1 【Notes】 I purchased and stored these as maintenance parts in the past. Although they are new and unused, there may be some minor scratches and dirt due to aging. Please consider them as outlet items. ※ There are no functional problems. 【Special Notes】 ★ Shipped via Yu-Packet Post.
