This is a set of press-in saddles (bridge pieces) for a synchronized tremolo unit found on Stratocaster-type electric guitars. The size (pitch) is 10.5mm. Included is a hex wrench for height adjustment. These were purchased previously as maintenance parts and are new and unused, but may have some minor scratches or dirt due to age 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 a delivery date or time, and generally takes longer for delivery than standard shipping. Please be aware of this. #Fender #FENDER
