Want to make a statement with your envelopes? Get the best sustainable choice. These Eco Friendly Envelopes are produced entirely from collected old paper. The paper is then whitened in a natural and harm free way without chlorine or optical brighteners. Did we also mention that the address window is biodegradable? You can even choose your closure, go with a self-adhesive strip or the more traditional way with a gummed seal. Personalise the enveloped with your logo or branding and your stationary is all set to impress.
