Can you buy pendulums that double as necklaces? That way you can carry it with you everywhere and when people see it they just think it's a cool pendant until you use it. Also, it's convenient, practical, has has another use. I was just wondering because I'd love to have a pendulum, but I don't want to have to deal with what some of my family would think/say and I also don't want to lose it. Also, is a pendul easy to use? Because I would like to learn how to use one and how to do scrying and other things you use pendulums for. (I honestly want to learn and study all aspects of positive magick and such.)
