These pendulums are made of resin and have stones that are inside of them that correlates with each chakra. The lotus flower on them also represents each chakra.
Pendulums can be used to connect to higher power and guides by asking it questions for guidance.
How to use a pendulum:
Hold the pendulum with your thumb and drape it over your fingers. Make sure there is no interference with the chain.
Ask your pendulum to show you no. The pendulum will swing a certain way, it may be back and forth or in a circle clockwise or counterclockwise. Different pendulums can have different answers. Whatever direction you get for your no that will be your answer for no.
Then you will ask your pendulum to show you yes. It is the same process with getting your no. Whatever direction you get that will be your yes.
After that you are able to ask yes or no questions. It can be as simple as "should I get a pizza?" It basically reaffirms what you are actually wanting to do by your energy. If you are getting a conflicted answer a trick I like to do is ask "can I get an unbiased answer" before I ask whatever it is I want to ask so that my energy gets separated from the question.
