Built for military professionals and units, the Hazard 4 Blood Type Marker mounts to both clothing and gear in a variety of ways. The flexible 3D graphics clearly display the accurate blood type, and will not fade or break down after repeated use, keeping the text easily legible to prevent misreading. These tags are made of 3D-molded triple polyurethane rubber, and use a snap hook carabiner to rapidly clip to an appropriate mounting area. For total versatility, these markers can be worn with a lanyard around the neck, sewn onto gear or even nailed onto hard surfaces. These markers are sold in packs of two with one carabiner, and are made with a raised guilloche pattern in the background for shedding mud and ice.
