I believe this Dekopin first pitch T-shirt is valuable. This is a set featuring a blue GILDAN T-shirt with a Decoy's First Pitch design and a keychain with a photo of Shohei Ohtani and Dekopin. - T-shirt design: Blue T-shirt with a Decoy's First Pitch graphic - Brand: GILDAN - Keychain: 1 with Dekopin and Ohtani Purchased at a pop-up store in Ikebukuro, it was the most popular design. I bought it even though only a men's size S was left, but I'm selling it because I wanted a looser fit. Width 46cm, Length 70cm It cost nearly 5000 yen. The tag has been removed, but it's new.
