My initial thought was that the little charms people were attaching to their stemware was gilding the lily, until my wife explained it was so that people would know which was their glass. Then it all made sense. A company called Il Bere has developed an industry around these charms by bringing a bit of high-tech to the dinner table.
The Il Bere charms differ from other brands because they use a very strong, very small magnet to hold the charm to the glass. You drop the magnet to the bottom of the empty glass and bring the charm up to meet it. Because the magnet is so strong it holds the charm in place on the side of the glass.
I tried it with a number of glasses and found it worked as advertised. Notwithstanding that, I would not use them at home, nor recommend them.
First, there are medical and safety warnings on the package that warn against the use of the product by individuals with pacemakers or internal medical devices. Unless you do a complete medical workup of your guests, you might not know. Why take the risk?
Also, the package warns against use by children under the age of 12. I would add to that "persons who are intrigued by how magnets could be used to hold through glass". You see, it is just too easy to imagine someone accidentally swallowing one of the ex-lax sized magnets.
Consider a person at the table, perhaps a person who has had a bit to drink, fidgeting with the charm. Next thing you know, the magnet has fallen into the glass, and then accidentally ingested. What happens next? I'm not sure. I suppose it might come out the other end, but imagine if it didn't! This could lead to a very dangerous MRI!
Yes, these are pretty. But, for me, they are pose an unnecessary risk.
