Tagger Micro Darts are the key Ammunition of the Nerf Dart Tag line. It is similar to a Whistler Dart or Sonic Micro Dart, but with velcro on the tip. This allows players' darts to stick on the vests given with each set, to keep score. Dart Tag Darts can not be used with Clip System blasters, as it will jam the blaster. The darts will get dirty if not washed because the velcro attaches to hairs or clothes.
