C5 Window Envelopes
C5 Window Envelopes (A5) – 229mm x 162mm
C5 Window Envelopes measure 229mm x 162mm and are sometimes referred to as A5 window envelopes. They are one of our most popular envelopes as the window allows the user to display the recipient’s postal address without the need for an address label.
We can supply C5 window envelopes in a variety of weights, colours, seal types and pack sizes both with and without a window. We also stock C5 envelopes from industry leading manufactures including Basildon Bond, Evolve, Postmaster, New Guardian and Plus Fabric amongst others. We also stock our own brand Q Connect C5 Window Envelopes which provide a high quality low cost alternative to the other brands we supply.
These envelopes are suitable for an A4 sheet folded once or an unfolded A5 sheet. They are also classed by Royal Mail as a small letter as long as the thickness is less than 5mm and the overall weight is less than 100g making it a great choice for controlling your postage costs.
