These 3 inch inside diameter white mailing tubes feature 3-ply spiral wound construction that delivers consistent wall rigidity, keeping rolled contents protected against compression and impact during transit and storage. White snap-on end caps are included and engineered to stay seated under standard shipping and handling conditions.

The clean white exterior makes these tubes appropriate for direct-to-recipient shipments across print distribution, architectural and engineering firms, photography studios, and retail fulfillment operations where presentation matters at the point of delivery.

The listed 20 inch length reflects usable interior space — the actual tube is slightly longer to accommodate end cap fitment. Additional 3" end caps are available separately for reuse applications. Each case contains 24 tubes.
