Buying Path

Buy first

Use SKU B855SS when the packed item fits the listed 12 x 8 1/2 mailer and no special listed spec is required.

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 material, color, closure/style, or pack quantity or workflow, compare B805SS, B83325PK, or B855SSTT25PK. If the finished packed item is tight on any side, do not force the 12 x 8 1/2 fit. Use a nearby size or finder page before ordering.

Default pick: SKU B855SS

Start with SKU B855SS when the packed item fits the listed 12 x 8 1/2 mailer and the order does not need a special listed material, color, closure/style, or pack quantity. It is the lowest shown unit-cost option in this matching set; compare the other SKUs only when their listed specs matter.

That makes it the clean default buying path for this exact size: simple spec, 100 pack, and no upgrade unless the job needs one.

When to switch
