Lasi may be elusive but she always comes home...
The word LASI, like the Chzech word SKLO, means glass.
the label you're looking at is Riihimäen Lasi - glass from Riihimäki. (be patient with te Fininsh, please)
so properly speaking, this is Riihimäki glass. Not just glass.
I admit, it is not obvious.
Nice vases, though!
