Sample approval checklist

• Record the sample model code, millimetre sizes and prism notes on one sheet.
• Photograph hinge feel and bridge rest only when the buyer needs that evidence for the bulk release.
• Write any substitute as a separate offer instead of folding it into the approved line.
• Keep optional budget currency and high-end / mid-range / budget / undecided preference as buyer notes, not verified factory grades.

These checks are procurement verification steps, not factory test certificates owned by this desk. Sample approval remains the buyer's decision before bulk quantity releases. Continue to send the requirement when the sample decision is ready.

Keep non prescription prism glasses on their own quantity line from a prescription prism program, even when the frame colour matches. A sample that changes hinge torque, bridge rest or packing is a new commercial offer. We coordinate the review schedule; you decide accept or reject. We do not invent MOQ, lead time or warranty during sample review, and we do not treat a company brochure as proof for the quoted SKU.
