To prevent that however, I've put together a special 'for cosplay' tin box. In this tin box, is everything I need for my hair ( except my wig cap) when I cosplay.
That includes hair pins and hair clips of miscellaneous shapes and sizes, elastic bands and safety pins.
Of course i don't use safety pins on my head, I'm just placing them in the case for easy storage.
So whenever I pack my bags for cosplay, this is the case I will always bring and be assured that everything I need for my hair is inside.
Hope this was helpful !
