Can you mail pepper spray to your daughter?

I don't see why not, however can't she purchase this where she lives? I would inquire at the post office or give them a call and ask. They would be the best to answer this question. YES, of course you can. PLEASE NOTE:

Pepper Sprays, or any type of weapon, including stun devices, knives and batons, cannot be shipped outside the United States withoutout proper permits.
