This is a head cover for a Blue Tee Golf driver. It has only been used indoors, and I think it's in good condition, but it's a used item, so there may be some overlooked areas. Please understand this before purchasing. - The material is neoprene, which is a stretch material. (In my personal opinion, it's easy to put on and take off, and I don't feel any stress.) - It's approximately 35cm long and 18cm wide. - The inside is acrylic boa. This item is just about the right size to fit in a Nekoposu box, so it may be shipped in the Nekoposu box as is. Please be aware of this beforehand. Thank you for looking.
