London GB Good service
The window C5's - window just in the right place to fold a letter in half and let the address show through.

Actual Envelope quality is not bad
The seal not good at all. We are having to reseal every envelope with cello-tape. That is an extra unexpected cost and we would not buy the envelopes again.
