The clear plastic envelopes I ordered were the wrong size! They were only 1mm smaller, width-wise, than was stated, and when I phoned up, Transpack measured one from their stock and confirmed that they indeed were the wrong size. Now, 1mm normally makes little difference but for me, it has made a huge difference when packing an envelope and a *portrait* greeting card into this plastic envelope. It is such a tight squeeze now that it takes about 3 times longer for each card. I was disappointed in Transpack's attitude: the duly sent me one larger plastic envelope to try, which, as I had already thought, looked rediculous. No mention of an apology or suggestion that they would try and get the correct size to me. All they said was "you can return them and buy them from somewhere else if you like" :(
