Review: Great product - fast delivery
Review: As some of the other reviewers said, if you want to send them as a large letter instead of a small parcel (saving about 50p per delivery) then you will have to tape one/both of the sides down, but given the value for money it is completely worth it as this only takes a minute for each envelope. Overall a great purchase and I would happily buy again.
