This is a long-sleeved T-shirt designed by Sho Kasamatsu, "Rock one's world," which I purchased a few years ago. I've worn it several times, but I'm selling it because it no longer matches my other clothes. Please note that the collar is slightly yellowed due to multiple wears. I believe the size is L, but I can't say for sure because there's no tag. Measurements are: Width: 49.5 cm Length: 71 cm Sleeve length: 60 cm It fits me perfectly, and I am 169cm tall and weigh 54kg. I will clean it as best as I can before shipping, although I am not a professional. I hope a fan will buy it.
