C5 envelope, 162 x 229 mm, white, silicone strip, 80 gsm, 25 pieces/set

White envelopes for correspondence. The envelopes are covered on the inside with a layer of color. This procedure is usually applied to white envelopes, made of low-grammage paper, and aims to reduce the transparency of the paper. The main advantage of internal printing is the increased degree of confidentiality, thus protecting the information inside the envelopes.
