Witches' bells are traditional magical charms, usually hung on doors or windows, made of bells, beads, and other items on a string or hoop to ward off negative energy, evil spirits, and curses, while attracting good luck, abundance, and positive vibes through their sound. These handcrafted items serve as spiritual alarm systems, with their chime believed to clear stagnant energy and create protective boundaries, commonly used in Wiccan and Pagan practices as housewarming gifts or home decor.
