What to know before buying

Listing details to confirm

The title describes a bridge saddle, while the model and package details call the pieces lower string nuts. The listed dimension string is ATW-7639, white 2 piece, rather than an unambiguous set of measurements. Confirm the part type, width, thickness, height, and shape against your original before ordering. The product description says dimensions may deviate by 1-2mm due to manual measurement.
