Which 2 x 18 mailers 50 pack should I start with?

Start with P2018K if you need a standard exact-size option and its product page details match your packing requirement.

When should I choose a higher board spec?

Choose a higher listed board spec only when the shipment or buying standard calls for it. Compare the exact product page details before standardizing an upgraded SKU.

What if my item is close to 2 x 18?

Measure the product after adding the packing material you actually use. If any finished packed dimension is over the listed inside size, choose a larger product instead of forcing the fit.

Can I reorder by SKU?

Yes. Reorder by the same SKU when the product, pack quantity, and packing workflow have not changed. Use the quote path for larger, mixed-SKU, or recurring orders.
