Author confidence note (MEDIUM) (name data quirk: Universe name for this SKU contains duplicated text ("…4 / Styrene Butadiene, ..5.0 liter, baffled bottom w / vented screw cap, Sterile, Indiv wrapped, 4 / CS")) likely a transcription artifact in the staging table. Spec content above reflects the de-duplicated reality.
