The job it is listed for
A mixed dispatch desk starts from the goods. A postal tube is for a roll: a poster, a plan, a wrap that must not be folded. Wholesale Packaging keeps Postal tubes as its own range so it is not picked as a deep carton.
Tubes are their own range. A square carton crushes a roll or forces you to fill the corners.
The line that is not a substitute
A book wrap is for a flat pack. A tube is for a cylinder. They are not two sizes of the same thing.
The length of the tube has to clear the roll, including any end cap the product lists.
Bringing it in
Studios that post rolls every week should keep the length they use, not a mix of leftovers.
On Wholesale Packaging, orders that include Postal tubes and are placed by 3pm are dispatched the same day. UK delivery is free on orders over £50 ex VAT. Stocked items can be returned within 14 days.
Open Postal tubes when you already know this line. Tubes are sold as that length. Check the pack count before you treat one tube as the product. Wholesale Packaging will still dispatch an order placed by 3pm on the same day.
