Select from a huge range of C3 Envelopes

If you’re looking to send A3 sized letters, then C3 envelopes are just what you’re looking for. Available in a huge variety of shapes, sizes and colours, our huge range of C3 envelopes is sure to contain something that perfectly matches your needs.

The specific dimensions of a C3 envelope are 324 x 458 mm or 12.8 x 18 in. Alongside the traditional gummed options, we also stock peel and seal C6 envelopes, A6 sized foil postage bags, and string and washer options for a more striking presentation. Looking to send wedding or christening invites? You might also be interested in our decorative butterfly envelopes, which come in a range of pastel hues.

Don’t forget that we offer next day delivery on all bulk envelope purchases. We’d also be more than happy to send you a free sample if you’d like to see our C6 envelopes first hand before you commit to a large purchase. For more information, please call us for a friendly and informative chat.
