These napkin rings have a beautiful, sparkling glass appearance. I purchased them about 10 years ago from a Western import goods store. They are transparent and very beautiful. I have not used them practically, but have displayed them as ornaments in a cabinet. Just by placing them, the pink flowers appear to bloom widely, so I displayed them with the image of glass artificial flowers. They have a solid glass weight and a strong presence. With ingenuity, I think they can be used for various purposes such as flower arrangements, interior decoration, objects, paperweights, etc. These are elegant and sophisticated glass items with a beautiful shine. They will add a touch of glamour to your table setting on special occasions.
