Tagger Micro Darts were the primary 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 hair(s) or clothing. They were replaced later on in the Dart Tag series by the Tagger Micro Whistler Dart. Special edition Tagger Micro Darts were also included in the Spider-Man VS. Venom Dart Tag set.
