Therapeutic pendulums work better if they are on a string (cord) than on the chain. However, as everything that works, a string may wear off with time and need to be exchanged. Alicja, as a provider of most of the Therapeutic Pendulums in North America, leads us through the process of changing the string. Alicja Centre of Well-Being is a wonderful source of the widest variety of Therapeutic, Remote, and Witness Chamber Pendulums. Her company gives an additional string as a gift with every Therapeutic Pendulum purchased! Enjoy!
