We've listed these extras separately so that you can order as many or few as you want.
How it works
Simply work out how many envelopes you'd like, and add to your order. All prices are at a flat rate, and there are no minimum quantities.
Specifications
- C5 envelopes measure 162 x 229 mm / 6.4 x 9 inches
- C6 envelopes measure 114 x 162 mm / 4.5 x 6.4 inches
- All envelopes are premium quality and peel and seal
C6 is the smallest size that Royal Mail will accept, and so we don't offer anything smaller.
