I bought a selection of 9 different briefs. They are all ok. It was the first time I bought this Seobean underwear, so not sure what i had to expect. And I'll have to say that the other ones I bought are more preferable, because they are low rise (briefs as well as boxer briefs). So I bought these for the 'classic' model and they are fine and also comfortable to wear.
I don't think I'll buy them again because now I tasted the large variation on this site, look very common.
