Abstract: One embodiment of a helmet 10, upon which markers 14 are used to add decorations to the plastic outer shell 12. The ink from the markers 14 dries quickly, and thereafter becomes waterproof and unable to be removed without the use of chemicals or without damaging the plastic outer shell 12 of the helmet 10. The decorations thus applied are able to withstand the expected rigors of sporting activity without being erased. In addition, a solvent based cleaning solution 18 and a means for applying the solvent based cleaning solution 18 to the plastic outer shell 12 of the helmet 10 is used to erase any mistakes in the decorations, or to erase them entirely, thereby allowing the user to re-decorate the helmet 10 whenever they so desire.
