Design decorative envelopes are a relatively small group of plain coloured envelopes including envelopes larger than the typical envelopes used for handing out and sending invitations. Our range of Design envelopes includes envelopes in sizes C5 which is the size of a traditional school notebook, and C4 - comparable to A4 among papers. Made from high-quality smooth coloured paper with a weight of 120g or 140g, i.e. a fairly stiff paper which is very important in case of larger envelopes. The closing flap is trapezoidal in shape, and the gluing method is HK - a removable self-adhesive strip. Perfect for slightly larger invitations, greeting cards and exclusive correspondence.
