This is a set of pressed saddles (bridges) for a synchronized tremolo unit, typically 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. However, there may be some minor scratches and dirt due to aging and storage. Please consider them as an outlet item. Shipping will be via Yamato Transport's Nekopos service. Nekopos delivers to your mailbox, does not allow for specified delivery dates/times, and generally takes longer for delivery than standard shipping. Please be aware of this. #Fender #FENDER
