How accurate are the images?
We make every effort to ensure that the product images we use are accurate and up to date.

We endeavour to ensure that all images are as close to the true colour as possible, however we cannot guarantee the colour representation is exact. There can sometimes be shade variations between different batches of envelopes. There can also be variations when viewing on different monitors/screens depending on the settings etc.

If shade is critical, please ask for a sample.

How do I know the envelope is the right size for my cards?
Generally the envelope should be around 10mm bigger than your insert. We offer samples of many of our products, should you wish to check the size or colour before placing your order.
