Give every sample a purpose
What Buyers Should Check in a Packaging Sample is best approached as a measurable packaging decision, not a visual preference. A stock reference sample confirms general quality and scale; a fit sample checks interfaces; a decorated sample confirms appearance; a pilot sample demonstrates the intended process. Label each sample with SKU, revision, date and open questions so it cannot be mistaken for final approval.
Compare like with like
When assessing several bottles, fit them with comparable pumps and caps and fill them to the intended level. Photograph and weigh each option, then record hand feel, label area, spray experience and carton impact. A simple comparison sheet makes subjective selection easier to explain internally.
Close the loop in writing
After review, send one consolidated approval or correction list. Update drawings, artwork and commercial terms to the same revision. The retained golden sample should correspond to the signed specification; verbal comments and messaging-app images should not become the only production instruction.
