[One item in Japan??] Mac Tools Work Shirt S This is an item for sale. It appears to be a work shirt distributed to a very limited number of van sellers at the Mac Tools new product exhibition held in the United States, and I have kept it carefully. (As far as I have checked, I couldn't find it as a product.) Although I haven't worn it, there are wrinkles. It's thin, so how about it for spring and summer?
