Like other formats, C4 envelopes are designed for sending professional documents, as well as brochures, magazines, etc. In general, this type of envelope is perfect for storing all those A4 sheets of paper without having to fold them. In particular, C4 envelopes are slightly larger than normal envelopes, making them ideal for storing official and professional documents, for example. In our online shop for paper envelopes and other packaging products, you have a wide range of C4 envelopes at your disposal so that you can choose the one that best suits your preferences.
