These are chewy sweets they do in Sweden. I can get some over the Internet, but not the cactus ones (which are my favourite). I saw one shop that sold only the Salvi flavour (which is basically licorice) so I bought four of those. At the airport, I found a shop with a much wider assortment of flavours so I bought 2 cactus ones and three random others.
Next time, I'll wait until I get to the other side of airport security before I buy them. They're almost half the price there, and you can get them in packets big enough to hold two packs of playing cards.
