Pros : easy to attach a glass cabochon or even use for resin
Cons : the soft rubberized part feels like plastic, and I try to avoid that for food and drink to avoid micro plastics
Other Thoughts : I have not used in a wine bottle, so I don't know if it will be prone to pitting, was a bit annoying trying to get the base glob to
a perfectly sized cabochon so it wasn't as fast as a pre made thing might suggest
