This is a T-shirt set by illustrator LAM. Both were obtained as used items. I personally haven't worn either of them, and they were stored in a closet after being displayed for a while. The black one is a T-shirt sold at the Anime Festival Asia event in Singapore. Size guide: shoulder width/body width/sleeve length/length Shoulder width: 50cm Body width: 53cm Sleeve length: 22cm Length: 74cm I think it's in pretty good condition. The white one is: Product name: LAM's first solo exhibition "Eyes and Thunderbolt" EYES & THUNDERBOLT T-shirts/WHT L size https://lamlab.booth.pm/items/1977107 Shoulder width: 50cm Body width: 55cm Sleeve length: 50cm Length: 72cm This one has stains (yellowing) around the neck and a general feeling of use. The white one originally cost 7000 yen. I think the black one was about the same price, so it's a great deal! I will compress both shirts to fit in a Yu-Packet Post package. Please understand.
