FAQs

Is the 125-pack the best value?
Yes — compared to the 20 and 25-pack options, the cost per envelope is considerably lower in the 125-pack.

Are these compatible with franking machines?
Yes — the standard envelope front works with most office franking machines. Ensure the envelope lies flat when franking.
