These are spare clips for the Hightail Bike Hair Protector, if you have more than one helmet. 

Multiple helmets? No problem. You can easily move your Hightail between your helmets by installing a pair of clips on each one.

Each pack contains four clips (two pairs).  

Also included is two ampules of 3M Primer 94. This maximises the adhesive strength and allows clips to be installed on the helmet shell or the plastic trim (whichever suits your helmet better).
