New and piping hot- Fun in the Sun solar-powered bands! SOLAR POWERED? Yes, solar powered. These bands are translucent white when indoors, but when you wear them in the sun, the colors change to pink, blue, yellow, purple, or green before your eyes. Back indoors, they change back to white again and again.  The Fun in the Sun pack contains an assortment of the following custom-designed shapes: Flip Flops, Beach Ball, Popsicle, Palm Trees, and a super-big double-sized Sunbather.  Stretchy Shapes bands feature unique designs, stronger and bigger bands, and 20 bands per pack.
