Rarely We Know Its Function
Well for you who often use pants certainly you are familiar with the existence of small bags and also small buttons that surround the bag, emm or maybe any of you who are not wearing pants? it's natural that you do not know. So what is the function of the small pocket? but to put the money may just fit a sheet of two, make nebis HP may not be enough, unless HP is the size of the seed.
Pretty sure the small pocket was designed back in the 1800's for people to carry pocket watches.
that's right, thanks for the comment@liquifire
