Interior trim parts are quite robustly built, but they can still get damaged. Trim pieces in the trunk tend to be the parts that get damaged most often due to the tendency for cargo to be thrown haphazardly into the back. This Corn Silk Beige OEM trim piece that connects the roof liner to the trim pieces covering both D-pillars is no exception.

If you find that yours is damaged to the point of having exposed jagged edges, or even if it's just unsightly, replace it to get the interior looking proper again.
