These are 2.75in / 7cm double sided acrylic charms with a rainbow metal lobster clasp keychain attachment. The front of the charm is smooth and features either Solid Snake and Otacon, Big Boss and Kaz, or Kaz and Ocelot. The backside of the acrylic is rippled and textured, and looks like water -- please look at the video and photo 6 to see what the acrylic is like!
