This is a New Era bobble hat featuring the popular Looney Tunes character, Marvin the Martian, in a large design! It's a cute hat in a color close to fluorescent green (though it may vary depending on your monitor, the image is close to the actual product), and can be worn by both men and women! The base color is black. I think it's quite valuable as you won't have many opportunities to get it in the future. Marvin the Martian is very popular not only overseas but also in Japan, and his fashion items are also popular! Image 8 shows the hat unfolded. Size: Standard adult size Diameter: Approximately 26cm From the opening to the top of the bobble: Approximately 28cm It has some stretch.
