This is a head cover for a Blue Tee Golf driver. Although it has never been taken to the course, there are some wrinkles and slight discoloration in the middle of the back. This is a used item, so there is a possibility that there are parts that I have overlooked. Please understand this before purchasing. - The material is neoprene, which is a stretch material. (In my personal opinion, it is easy to put on and take off, and I don't feel any stress.) - Approximately 35cm long and 18cm wide. - The inside is acrylic boa. - There was originally a tag inside that said "MADE IN CHINA", but I cut it off because it got in the way when putting it on and taking it off. You may see a pattern like tree rings in the photos, but this is due to the light that entered during the shooting, and the item does not have such a pattern. Thank you for looking.
