Triangles are a symbol of the divine, and in particular, the divine feminine. A trine is a grouping of three. Astrologically, it refers to ways that planets come into alignment with each other, which indicates ease and accomplishment. Basically, a trine represents all manner of good things.
Wear these to remind yourself of your own divinity, and that all manner of wonderful things are coming your way.
Wear these three different ways -- short end in with a rubber backer, or with the short end at the bottom with the opening at either the front or the back.
