Exact RM5W Specs

Best Fit

• Purchasing teams that need the exact 9 3/4 x 12 1/4 in chipboard mailers identified by SKU RM5W, including the same pack quantity and live product route.
• Mailrooms and pack stations using flat document, catalog, photo, media, or rigid stayflat mailing workflow where a flat rigid mailer is preferred over a flexible envelope or full carton.
