The wise front-line soldier's practice of field-marking one's blood-group on the boot-heel (typically with duct-tape and felt-marker), inspired this Hazard 4(R) exclusive blood-type plaque. The 3-d injection-molded rubber marker is far more durable than the traditional solution since it cannot be wiped off, scratched-off, or dissolved by most solvents.
A more professional choice for a unit or individual operator in its appearance, it, more importantly, prevents misreading (imagine B+ becoming B- after some trail-wear). The form-factor allows multiple fast-mounting methods. In keeping with the on-boot tradition, weave them into boot laces, either horizontally, vertically or diagonally (slotted holes allow for different lace-hole spacings).
Wear them like/with dog-tags (i.d. medallions) or on a lanyard around the neck. Use paracord to make them into a bracelet. Sew them onto clothing/gear or Velcro(TM) backing using the perimeter trench. Or clip them anywhere since they are sold with a durable aluminum black carabiner. They come in sets of two with one clip in a variety of subdued colors and feature a raised guilloche pattern in the background to break up mud/ice.
They can even be screwed, riveted, grommeted, or nailed onto hard surfaces such as plastic cases, wooden crates, etc. to mark personal gear or a paramedic's blood supply. Also available in glow-in-the-dark. Specify blood-type when buying.
