C6 envelopes (A6)
C6 envelopes are a universal size, designed to take an A6 sheet without folding, an A5 sheet folded in half, or an A4 sheet folded in half and then half again. C6 is approximately a postcard size. C6 envelopes are also referred to as A6 envelopes.
At Bureau Direct we stock both portrait and landscape C6 envelopes in a range of colours to add a little vibrancy to your everyday stationery collection. If you’d prefer an envelope that makes a striking first impression, our metallic foil envelopes tick the box.
