Record the sample identity
Assign a product code or project reference, revision date and image set. Keep one approved version so later comments do not refer to different samples.
Check measurable features
Record dimensions, piece count, pack weight, assortment ratio and label placement. Use tolerances only when they have been discussed and approved.
Review appearance consistently
Compare color direction, surface finish, print position, glitter distribution and visible defects under a repeatable viewing condition.
Control every change in writing
After approval, document requested changes, affected files and the new revision. A chat message alone should not replace the final approval record.
A sample approval is an operational reference. It does not replace product-specific laboratory testing or market compliance review.
