Spec Check
Case verificationeyewear cases
Use this Spec Check page to resolve open choices on eyewear cases dimensions, shell material and standard markings on accompanying frames before you accept an alternative factory offer. Check frame size against the case cavity, lens specification only when the brief includes lenses, and standard markings on the quoted eyewear model—not on the case alone.

Fit and marking checks before accepting an alternative
| Check | Why it changes the quote |
|---|---|
| Cavity vs frame size | Lens width and temple length must fit the quoted case |
| Shell and hinge | Clamshell, zipper pouch or dual-compartment changes tooling |
| Marking on eyewear | Z87 or similar belongs only to the named eyewear model sheet |
Before accepting an alternative, verify whether the substitute changes outer dimensions, foam density, hinge type or logo placement. A cheaper reply that swaps a single-compartment shell for a double layout is not the same eyewear cases line. Ask for the documents that cover the quoted item rather than a generic factory brochure. Markings such as Z87 apply only when the named eyewear model sheet states them; they do not transfer to the case SKU automatically.
Selection checks that change the comparable quote
| Check | Buyer confirms | Why it matters |
|---|---|---|
| Outer L / W / H | Millimetre values on the sample | A one-size claim is not the same offer as marked sizes |
| Compartment layout | Single, double or pouch | Layout swaps change fit even when colour matches |
| Lining / cloth | Included or excluded | Silent omissions break landed-cost comparisons |
| Frame marking | Only if the named eyewear sheet states it | Case quotes stay separate from safety eyewear lines |
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.
