MULTICOLOR: Bright acrylic beads, some faceted, some smooth mix with plastic silver round beads and rhodium-plated cast metal spacers. SILVERTONE: Plastic silver round beads, some smooth, some etched with flower patterns with rhodium-plated cast metal spacers.The stretch cord is a reassuring 1mm and the cast spacers give these bracelets a good heft. Sized for most adults and some for even kids to wear. They can be worn as a bunch on one arm for fun, or taken apart and used in craft and beading projects. Great for party favors, cheep enough for kids parties!
