Our C3 manilla lightweight board-backed envelopes are designed to fit A3 documents and have a 120gsm manilla paper to front printed with 'Please Do Not Bend' and stiff back for support and protection.
The stiff back is made from a lighter board material providing great protection but with weight saving of approx 0.5 grams per envelope when compared to our regular C3 board backs envelopes.
Making this the more economic choice when trying to save on postage costs.
