Skol appears to be the name of a range of Aseda Glass - as described here (scroll down) as 'Skol - (Small Stones) Series'

Possibly the design of this series of 'Skol' are items with the base as shown in this link.
Does the base of your vase look like these?

If so, then yours might be a 'Skol' series vase imported by Milnor, designed by Joseph Bourne for Denby and perhaps made at Aseda.  Or ASeda might have made these Denby designed pieces which were imported to the States by Milnor but they might NOT be the 'Skol' series. They might just look quite similar to it.
 They also might NOT have been made by Aseda - the design might just be very similar to these 'Skol' series pieces which were made by Aseda.  i.e. sellers might just be attributing them to Aseda because the design is very similar ... if you see what I mean.

Some written source information would be needed to be sure they were made by Aseda, especially given the Dallas museum info in that American Glass book  just says made in Sweden but maker unknown.

I will check that out. Thank you:)

The seller does not give any reference for their attribution.

I find it a little bit difficult to work out how the glass was made in both Poland and Sweden, and I rather suspect the seller was putting as many "names" in as they could to try to get views.
I'm never sure of the word "rare". It could mean 50,000 or just 1. And I think the set is rather overpriced.

Thank you for your detection. Not sure if this already posted -- Dallas didn't come up in my googling, but I'll check them out. Makes sense that Milnor is the importer as it's on the paper label. Others have ascribed design to Bo Bergstrom. This ebay listing shows a bar set, asking $225, for: "Rare Swedish Glass Martini Set In SKOL Plum/Amethyst Denby Milner Aseda Sweden" --( this and other listings used the word SKOL):

I have come across a snippet of information from the Dallas Museum of Art.
They apparently have some glass which from the snippet I've found on google I think is identified as 'designed by Joseph Bourne for Denby, imported by Milnor Cincinatti, made in Sweden by unknown maker'.  The source is China and Glass in America 1880-1980, from Table Top to TV Tray
So perhaps Milnor was an importer in the States?
Perhaps contacting the Dallas Museum of Art might help with further information if they have any?
