Review on Crystal Magnetic Stemless Glasses Identifiers by Jonathan Abreu

Pros: Very pretty, unique, strong magnets Cons: Incredibly small - difficult to pour and remove from wine/champagne glasses; I was also very concerned that a guest would accidentally swallow one of them. They must be placed high on the glass (which increases the risk of suffocation), because if placed too low, a person's hand can knock off the stone when attempting to lift the glass. I will not buy again - impractical to use.
