Product Review

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-moulded rubber marker is far more durable than the traditional solution since it cannot be wiped off, scratched-off, or dissolved. A more professional choice in appearance, it more importantly prevents misreading (like B+ becoming B- after some trail-wear). It allows multiple fast-mounting methods. Weave them into boot laces, either horizontally, vertically or diagonally (slotted holes allow for different lace-hole spacing's). Wear them like/with dog-tags or on a lanyard around the neck. Use paracord to make them into a bracelet. Sew them onto clothing/gear or Velcro-backing using the perimeter sewing-trench. Or clip them anywhere, since they are sold with a durable black aluminum carabiner. They come in sets of two on one carabiner in a variety of subdued military colors and feature a raised guilloche pattern background to break up mud/ice. Then can even be screwed, riveted, grommeted, or nailed onto hard surfaces such as plastic cases, wooden crates, etc. to mark personal gear or paramedic's blood supply. Also available in Glow-in-the-dark. Specify blood-type when buying.
