Avon Kosta Boda barware?

I came across this glassware set in an auction lot and struggled to find information on them. They were simply stored in a box labeled “Swedish glass” and all wrapped in newspaper from the 80s. I finally landed on Avon Kosta-Boda glassware but there are no noticeable markings anywhere on my glasses. They have no “seam” lines (making me think they were hand blown) and there are a few imperfections among the set of 44. I’m struggling to find any information on how to confirm these as Avon Kosta Boda glasses and also figuring out a price point for resale.
