Stick-on hook for hanging small glass candleholder from a beam in the ceiling?

Question

I want to hang these glass candleholders from a beam on the ceiling, but the beam is made of concrete. So I need to use a stick-on hook...anyone can recommend a hook to use ? And, how to attach the candle holder to the hook? Is fish string or wire better?

The glass candleholder is this:

Seeing that you are planning on gluing to concrete you may have to use an epoxy for adhesion. I would not use fish line due to the candle heat. a very thin wire would be safer
