It's cheap enough for me. It's large enough for me to dry four onaholes with each of its four corners. Says made in China on the wash tag, but seems to be designed in Japan. Two per bag. Basically, it's decent and does it's job, but you could probably find something just as good elsewhere (if you're not as lazy as me)
If you want to get serious about onaholes these are essential
You get two high quality microfiber cloths. you could probably get them in your town or whatever but it doesn't feel nearly as cool as getting the neat japanese logo. besides that there an essential tool for proper cleaning and maintenance
