"Soyan no Namako-chan" men's T-shirt. A sea cucumber design is featured on a yellow T-shirt. - Color: Yellow - Design: Illustration and text of a sea cucumber - Year of manufacture: 2018 - Region: Taito-ku, Tokyo. Size M. Shoulder width 46.5cm / Body width 47.5cm / Garment length 64cm / Length 56.5cm / Sleeve length 18.5cm. Measurements are approximate. 100% cotton / Made in China. This item was found among my late brother's belongings. I believe it was merchandise from a collaboration event between Soya City, Hokkaido, and Taito-ku, Tokyo, perhaps a sister city event. I think my brother received it as a souvenir. It has aged, but I find it interesting due to its vibrant color and unique design. The back says "Namako-kun." It doesn't fit me, so I hope someone who appreciates it will take it.
