WS-PN02 color-coded pen needles help procurement teams organize needle SKUs for professional channels — including disposable insulin pen needle assortments used with GLP-1 and Peptide-compatible pen injectors. Clear visual coding can reduce picking errors in clinic and distribution workflows when multiple lengths or gauges are stocked.
As with all sterile accessories, packaging integrity and lot traceability are part of supplier evaluation — not optional extras.
