Window Envelopes

Window envelopes for your business, home and office are such a time saver. The clear window in the front of the envelope allows the letter/invoice address to show through the window therefore saving time and potential errors by getting the wrong contents in the wrongly addressed envelope. Available in either white or brown/buff manilla and sizes ranging from C6, DL to the larger C4 sizes in gummed or press seal there is plenty of choice to find the envelope to suit UKs largest manufacturers stock, which are not all listed on our website.
