Caution: Do not finalize your order with this seller unless satisfied. Rushed orders, no upfront details, and an alarming tendency to ignore necessary changes. There's a concerning issue of racial profiling and blatant dismissal of revision requests. Exercise extreme care when dealing with this seller!
