You obviously have little knowledge about rs and most of your pricechecks are ridiculously low. A barrows pure is an account with 70-75 defence. The account is 63 defence so it can be easily turned into one. As long as attack is over 70, its called a barrows pure, if its 60, then its called a mid-level pure.
OT: the account is worth around 70m imo, the rs market is kinda dead atm
