* Depending on product batch, these may come packaged in bulk or in clamshell packaging (depends on how FailZero sends them to us).  They are the same exact brand new part, regardless of packaging style.  Also: The FailZero BCG's tend to be grey/silver in color and are not shiny/polished and sometimes the carrier logo is slightly faded, but still visible.  Feel free to request a certain packaging style when ordering and we will ship as requested, if that packaging style is available.
