A quick Google search uncovered that Seibei is a company that makes t-shirts. It had originally seemed as if the image to the right might end up on a t-shirt – and maybe it did. But if it did, then M.U.S.C.L.E. collectors may have missed out.
However SEIBEI does currently have a M.U.S.C.L.E.-inspired t-shirt for sale. The design is rather basic, essentially applying the M.U.S.C.L.E. logo design to their SEIBEI company name. The t-shirt strays away from the classic Yellow and Blue and replaces it with a Pink and Bright Blue combination. It is a bold choice that will likely cause intense love or hatred from M.U.S.C.L.E. collectors.The $23 price tag might be more than many collectors want to pay for a t-shirt, but the shirt appears to be a higher quality t-shirt. And $23 isn’t too bad for independent creator-based apparel.
