Have you seen the size of the label they have to attach to the package though? I sold a few nail polishes on eBay last week, wrapped in bubble wrap and into a small Jiffy bag, printed my postage and off to the Post Office, told them they contained nail polish so needed a warning label etc. Well, I then got a b******ing from the guy at the post office who produced a label that was almost A5 size (basically the same size as the damn Jiffy bag!) "I need to get this on the front of the package, you need to use bigger Jiffy bags or something else, i'll accept them this time, but won't next time" he was promptly told I would not be using bigger packaging for one nail polish as it was just ridiculous. It's almost like Royal Mail are putting people off using them. I'm now looking into using Hermes for everything from now on.
