1.5” Diameter A3 Size Postal Tubes 13” Long - 330mm Long x 38mm Diameter

Super Quality A3 Postal Tubes 330mm Long x 38mm Diameter. 

When you are looking for the cheapest A3 postal tubes that don't compromise quality in any way, our great quality British made postal tubes with a slightly narrower 38mm diameter are just what the doctor ordered. They provide superb protection for things such as: artwork, prints, documents, posters, maps or decals. They can of course be used for other rolled items or non paper narrow items.

You will find these quality paper / cardboard mailing tubes within our 1.5mm wall - ‘Standard Strength Range' provide a very high degree of protection in the postal system for many rolled items. The 13” 330mm / 38mm narrow diameter of these postal tubes allows them to pass through most UK letterboxes. Curling of items before postage & after mailing out is slightly greater with these narrower diameter postal tubes but more than acceptable to many customers. If you are concerned about curling and want to check out 2" 3" or 4" diameter tubes then visit our other mailing tubes

The overall length of the postal tube is 33cm / 330mm appx 13” long. Allowance of about 25mm should be made for the insertion of end caps. Another advantage of our 38mm diameter postal tubes is that they can be posted through the vast majority of letterboxes in the UK. Some British letterboxes do accommodate wider diameter tubes but if you are attempting to minimise the number of mailing tubes that need to be left in a safe place, with a neighbour or require a redelivery attempt then 38mm cardboard tubes is a great option.
