Greetings,
I think it would be a good idea if we have different colours of this kind of mask (Image below), such as red(#DC143C), blue(#0000ff), white(#FFFFFF), orange(#FFA500) and pink(#FFC0CB). However, I am not sure whether Mike can make modified balaclavas.
The cost of these coloured masks will be the same as the black mask that currently exists in every clothing shops.
