EXTRA STRONG 2mm Wall Postal Tubes - Heavy Duty Postal Tubes


These Heavy Duty thicker walled postal tubes provide a stronger alternative to the more common 1.5mm walled postal tubes for those who require a little more protection for the items they are shipping. They may however, due to their extra weight move your postings into a higher Royal Mail price band.
