Upgrade only if

Move away from the default only when the live product page lists a spec your order actually requires.

Switch size if

If the issue is exterior, style, depth, material, or board spec or workflow, compare BINB912. If the finished packed item is tight on any side, do not force the 9 x 12 x 4 1/2 fit. Use a nearby size or finder page before ordering.

Default pick: SKU BINMT912

That makes it the clean default buying path for this exact size: simple spec, 50 pack, and no upgrade unless the job needs one.
