Despite, that analytics says that there is a start of the global economic crisis, there is a business that is on the rise:
Manufacturing of Masks.

For example URBAN AIR MASK 2.0

https://www.airinum.com/products/urban-air-mask-2-0-classic?variant=13654585606249

This manufacturer is out of stock. His fancy designed mask cost 69 USD. It is reusable, with filters.

The original cost of such a mask, I believe small. Margin-profit should be very big. Looks good for business in a time of viruses spread and ecology problems.

What do you think? Is it worth of starting such a business? And if yes, what will be necessary for this? What kind of investments? What kind of competence? And how to scale such enterprises nationally and globally?
