These are trolls by Bergdala Glasbruk of Sweden. See the picture below.

Bergdala have been going since 1889. Here is there their website;
http://www.bergdala.com/vandrarhem.htmlThey operate very much as a tourist attraction as most glassworks do in Sweden. They even have their own restaurant and youth hostels! There is not much info on the glass at all!
Hope this helps.
