They are not that popular here, but you can find some every now and then. I saw some in the Neste gas station's K-market in Suomenoja, but that was a month ago. But... that means that the K-stores might have them.
I've seen them in 3 places today in Turku.. Stockmann, Prisma and a candy shop. Seems they are everywhere! "Made in China" though so I don't know if I'd eat them after decorating the tree with them!
