Mailing tubes are cylindrical containers designed for shipping and protecting documents, posters, blueprints, and other items that are best kept rolled rather than folded. Made from durable cardboard, these tubes ensure contents remain secure during transit. They come in various sizes and lengths to accommodate different items, and some feature plastic end caps to securely seal the contents. Mailing tubes are an ideal solution for businesses and individuals looking for a reliable way to transport papers and materials without creases or damage.
