Unless there's actually a law that classifies them differently than pepper spray then it would just be a "restricted" item on ebay:
Some personal defense items, such as pepper spray and mace, can be listed as long as you follow the law on the sale of these items. Before buying or selling these items, check your city and state laws.
Note: While I would love to take credit for his work, I am not associated with Mad Customs!
