Vintage Vetravir Italy Glass Set Unique Octagonal Shape Glassware

I have over 200 listings on this site and some vintage items so please look at my other sales. This is a set of six vintage uniquely-shaped glasses. The sides are in an octagon shape. They were made at least before the 1950s as they belonged to my great aunt and uncle and were kept in a China cabinet. There are no chips or marks so they are in new condition. There is a tiny maker's mark with a tiny encircled backwards "R" that can be read correctly when you look down into the glass. It appears to also say 'Vetravir" and "Italy" on very careful inspection. I believe each one of these was supposed to be a spoon holder but I like them much better as a set of glasses as they are very easy to hold with the octagon shape. They are a little over 3 and 1/2 in tall.
