Best Fit

• Purchasing teams that need the exact 12 x 9 x 3 in corrugated mailers identified by SKU MLR1293, including the same pack quantity and live product route.
• Pack stations using small parcel, ecommerce, returns, or rigid mailer workflow where a rigid corrugated mailer is preferred over a flexible envelope.
