High-performance golf shaft with SR flex, made by Callaway and Mitsubishi Chemical. - Brand: Callaway - Design: Mitsubishi Chemical - Flex: SR - Model: Shaft Grip has a thumb grip mark. Purchased on Mercari about 2 years ago. The description at the time stated it was the original shaft for a Rogue ST MAX driver. I also used it with a Rogue ST MAX driver. Used about 3 times a week. I've marked it as having some scratches and dirt, but other than the thumb grip mark, I don't think there are any noticeable scratches or dirt. Thank you for viewing.
