This is an aftermarket product imported from overseas. It's a set of 6 vintage-style, steel-pressed saddles for a Stratocaster. They have a slightly thin stamp, like Fender Japan (or was it Mexico?), making them perfect for enjoying the vibe, even if it's just a "look-alike." However, unlike Fender Japan, where the stamps are oriented in opposite directions, these have the same orientation (both facing the opposite direction) as those made in the USA. Chrome-plated, the saddles are approximately 10.3mm wide, with M3 set screws that are about 10mm high. The saddle thickness is 1mm. An adjustment L-wrench is included.
