How can I be sure that I am ordering the right bag?

Double check the measurements against your product, remembering that these bags are flat and if your product has depth that will impact on the width you need and you could well need a wider bag than you think. If you need help give us a call or contact us via the online chat. If you are still not sure which size you need we can send you a sample to test – please email with your request, and don’t forget to give us your address.

What is your returns policy?

If you do happen to order the wrong bags or you find it is not suitable after all we will happily accept them back, unused and in a saleable condition. You will need to call us right away and request a returns number. We will need to receive the bags back within 14 days of when you received them. You will need to send them back at your own cost but once received we will make the refund to you quickly.
