Pepper Spray in Busan

Hi there,

I just found out that a friend of mine was jumped by some random guy the other day as she was walking down the street. From what she told me, it was completely unprovoked and she is the second of my friends that this has happened to. She showed me the big bruises on her arms and eye and she said that he tried to choke her. I feel like she should have more protection with her. I know that pepper spray/mace is legal in Korea but does anyone know where I can buy it in Busan? Has anyone seen it anywhere?

Any help would be greatly appreciated.

Thanks
