From the M1GO site - Unfortunately, they are listed as 'approximately 1/2 scale.' If they were full-size I'd be all over this, especially the green (machine-translated as 'Clay Color') ... at half-size, I'm not so sure. (OTOH, I definitely want to encourage the Sofubi makers to continue to issue special 'Clay Color's!)
nice but what bother doing a half size? I like the clay one to, if it was full size you can put it between so noh mask
