A Negative Blood Type Marker

Features

1. Two-Piece Marker Set — Each pack includes two A Negative markers so you can run one on your boot and one on your gear, vest, or pack.
2. Injection-Molded Rubber Construction — Solid 3D rubber body holds up to weather, abrasion, and solvents that destroy duct-tape-and-Sharpie field markings.
3. Boot Lacer Channel — Slotted design threads directly onto standard boot laces and seats flat against the tongue or heel.
4. Included Carabiner Clip — Comes with a small carabiner to attach the second marker to MOLLE webbing, zipper pulls, plate carriers, or pack straps.
5. High-Visibility A- Marking — Raised, contrast-color blood type lettering stays readable at a glance for medics and first responders.
6. Won't Wipe or Scratch Off — Permanent molded lettering cannot smear, fade, or dissolve like ink-on-tape markings under sweat, blood, or fuel.
7. Low-Profile Footprint — Compact size adds critical identification without snagging on gear or printing through uniform layers.
8. Multi-Position Mounting — Lace it, clip it, or zip-tie it — works anywhere you need fast, repeatable blood type ID across your kit.
9. Hazard 4 Build Quality — Made by Hazard 4, a recognized name in tactical accessories and load-bearing gear.
