Nothing wrong with the seals purchased, but arrived late (which was a major pain) despite paying extra for 1st class post. When I enquired why it was late, I received an email saying I should've paid £8 for next day delivery and their guarantee for 1st class is five days! Well, don't offer a 1st class option, then. I suspect their despatched time is actually the packed time, not the time it's actually passed to the post office. I might use them again, but I'd think long and hard.
