Envelope in envelope - that's 15 envelopes packed in another envelope. The product is ideal for freelancers and small businesses who want to add a sustainable touch to their correspondence. In fact, there is no other plastic-free envelope set on the market. The recycled paper itself carries the Blue Angel label and is manufactured in Germany not far from where we are located. Each envelope set is hand-packed at a local integration company - Elbe-Werkstätten.
