Eco friendly padded envelopes that are stuffed with post consumer recycled fibre actually use MORE material than our envelopes and are considerably slower to pack, yet do not provide any additional protection or cost savings.

This range was co-developed with one of the Internet's largest retailers... so you might recognise our envelopes!
