Sending posters, artwork, or prints? These cardboard postal tubes keep them safe and crease-free. Each tube is 450mm long with a 3-inch diameter, and they come with tight-fitting white plastic end caps to secure your contents. Made from strong brown Kraft paper, they're more durable than standard recycled tubes and have a professional look. Use them for mailing A3, A2, or even larger rolled items, or for storing blueprints, maps, or banners. They're also handy for protecting long items like fishing rods or golf clubs during shipping. This pack includes 100 tubes, so you'll have plenty for multiple projects or business needs. A reliable, cost-effective solution for anyone who needs to ship or store rolled materials securely.
