Sorry for the small photo. Look close at the writing in blue, or just follow the link to buy some. If you are in the UK.
Saw a box of these on a TV show this evening, and Alison said they have been sold forever, even in Canada. Apparently, common in all the english-speaking countries except the US.
Sure, they also sound useful, in that they are gigantic, but who cares? The name is funny enough.
