These bobby pins feature a dichroic glass gem come in four different colors. Dichroic glass is a lovely, sparkly, color-shifting glass originally invented by NASA. If you look at all three photos, you should be able to see the colors shift, as the bobby pins are in the same order throughout. (Sky blue/blue on the left, pink/purple next to it, orange/red, and emerald/purple on the right.) The price is per bobby pin.
