Standard envelopes with window | C5 format

If you need to send communications to your customers, postcards or administrative documents, you can use C5 format letter envelopes. The envelopes are internally printed and this allows for the protection of sensitive data, which is not visible from the outside. The closing flap has a practical adhesive strip that allows you to easily seal the bag. Personalize your C5 envelopes now with original graphics and get them noticed!
