I have 6 of these, I always thought they were to serve honey, but was told they are not??
they are 4 1/2" long, the end that is more "cut crystal" has a blunt end like it was ground down. It looks like there is a seam down the center. Sitting on there side they tend to roll - can't be knife rest, yet they dont stand on either end on there own. The ridged part looks darker/discolored like they were baked in something??
Things I thought of but can't find anything the same on google images :
glass mortar (and pestle)
glass honey dipper
glass popsicle handle
