Frequently bought with

Common questions

Will the caps stay on during shipment?
Yes. The white end caps snap securely into place with sufficient grip to prevent accidental pop-off during standard carrier handling and transit. They provide reliable closure for mail and parcel shipments.
What's the difference between usable space and actual tube length?
Usable space (18") represents the interior cavity where your contents fit. Actual tube length is longer to accommodate the depth of the snap-fit end caps, ensuring secure sealing without compression of materials inside.
Can I reuse these tubes?
Yes. The 3-ply spiral wound construction is durable enough for multiple uses. Many customers refill and re-mail these tubes, reducing packaging costs over time while maintaining structural integrity.
Are replacement caps available separately?
Yes. Additional 4" end caps are available for purchase separately (SKU: PMTCAP4-C820), allowing you to extend the life of tubes or stock caps as needed for inventory management.
