My husband bought this about 20 years ago at Universal Studios Japan. He tried it on for a short time about twice and kept it carefully stored in his closet. The size can be adjusted with the strap in the back. There is no stickiness, odor, or fading due to age-related deterioration, but please refrain from purchasing if you are looking for perfection or are concerned about minor details, as this is a vintage item that has been stored at home. With the above in mind, this is a rare and cherished cap that I have had difficulty parting with. I would be happy if it could be passed on to someone who loves the movie BACK TO THE FUTURE. Please feel free to comment if you have any questions. Thank you very much.
