C6 Envelopes (A6)
Here you can find our huge range of high quality C6 envelopes. Our C6 envelopes come in packs of 500 and 1000, as well as smaller retail packs depending on your requirements.
Within this range of A6 envelopes we have a range of colours including manila and white C6 envelopes available. There are a few different closure options available which include peel and seal, gummed as well as self seal envelopes. There is also the option of plain or windowed envelopes. Window envelopes have a window cut out in the front to see the address details printed onto the letter itself, where as plain envelopes would require a separate printed address label or an address to be written on the front.
All of our envelopes are from top brands including Basildon Bond, New Guardian and Blake, giving you good quality envelopes each and every time.
We have a huge variety of envelopes sizes available- if you need help finding the right size for you, please feel free to give our friendly customer service team a call.
