Missing item_specifics_05_stamp_format for guideline pairs, joint line pairs, etc.
If plate number coils made the cut, guideline pairs, joint line coil pairs, paste-up pairs, and cross gutter blocks should be added. Coil line pairs would have more commercial impact than plate number strips I recall eBay suggesting that I list a red-orange stamp as "orange" for "better visibility". I prefer credibility over visibility. Listing coil line pairs as "pairs" seems unnatural.
