First off, why would Momotaros fetch a high price from thrift when you can go to multiple stores online to get them at cost. Secondly I don't know what your point is, that I wasn't aware that in 2011 they came out with a 20oz jean that they planned to make part of mainline production but quickly went defunct and unheard from again? WOOPS.Bro, Momos are so rare in a thrift, here. I've yet to come across a pair. Did he thrifted those? If so, those should fetch a nice price as they have a big following.
