This is a set of press-in saddles (bridges) for a synchronized tremolo unit, typically found on Stratocaster-type electric guitars. The size (pitch) is 10.5mm. An Allen wrench for height adjustment is included. These were purchased previously as maintenance parts and are new and unused, but may have some minor scratches or dirt due to aging and storage. Please consider these as an outlet item from a third-party manufacturer. Shipping will be via Yamato Transport's Nekopos service. Nekopos delivers to your mailbox, does not allow for specifying delivery dates and times, and generally takes longer for delivery than standard shipping. Please be aware of this. #Fender #FENDER
