These B1 Wide Postal Tubes are perfectly sized for sending B1 documents and papers through the post and courier networks. Suitable for multiple sheets of loosely rolled paper, our wide postal tubes are supplied with snug fitting end caps and ensure ultimate protection during transit. An eco-friendly solution, these postal tubes are made from 100% recycled fibreboard, are fully recyclable, reusable, and can be biodegraded without the end caps. Our cardboard tubes can also be cut down to create a specific, custom size and you can buy additional end caps separately, ensuring all your needs are covered.
