Exact MTM218 Specs

Best Fit

• Purchasing teams that need the exact 18 1/4 in white triangle mailing tubes identified by SKU MTM218, including the same pack quantity and live product route.
• Mailrooms, print shops, fulfillment teams, and art/document workflows using rolled document or poster mailing workflow where a tube protects rolled items better than a flat mailer.
• Reorder workflows that need a stable product page, reorder path, and bulk quote path for recurring mailing tube buys.

Not Ideal For

• Flat documents, folded goods, fragile items that cannot be rolled, or products that need a box, stayflat mailer, or cushioning instead of a tube.
• Items that need a different tube diameter, length, color, cap/crimp style, wall/board details, or pack quantity.
• Substitutions based only on one matching dimension. Confirm both diameter and usable length before switching tube SKUs.

Before You Order

• Confirm SKU MTM218, usable dimensions 18 1/4 in, product title, material, closure style, and sold-as quantity.
• Measure the item with any insert, tissue, padding, literature, or return paperwork that must fit inside the mailer.
• Check the live Packrift product page for current price, stock, and delivery options before ordering.
• For larger or recurring orders, include SKU MTM218, quantity, destination ZIP code, timing, and related mailer SKUs in the quote request.

Nearby Checks and Substitutes
