Kalimar Strobe for Polaroid SX-70 is a shoe mount flash designed for use with Polaroid cameras. The strobe light type provides a powerful burst of light for high-quality photos.  This was found in my in-laws stuff in the box and do not know for sure if it is working order.   The box has some water damage and is missing one side of the box.   If you have any additional questions I can figure out for you please message me.  I don't really know much about this product.
