The dent was added by cutting a hole and adding the dent...as you can see in the PP2 helmet its very shoddy work....
The Helmet is Fiberglass also not ABS. Dont recall if we know who sculpted it though?
Do we know any more information about who added the dents or how they were made? I recently messaged Sandy Dhuyvetter and she said that the helmets she painted arrived to her with the dents already in them and still white.
