My favorite is the Finest Touch EX model. It is a semi-bikini design. You might think it looks old-fashioned but putting a pair on will give you an instant erection the way they feel and look on you!
What makes them so special is they are made of genuine Japanese cotton which feels softer than any other type of cotton. The cut also accentuates how full your eggs look and super defines your butt


Both are nice actually, and one feature of the Thai version is that it only has a one-ply back instead of two, so the Thai version can be pretty revealing, especially if you happen to swim in them like I sometimes do

With the Finest Touch briefs you can always tell if they are from Japan or Thailand by the stripes on the waistband. From Japan, there are three stripes and from Thailand, there are two.
