They are selling masks claiming they protect the wearer from coronavirus when they don't allow the wearer to actually breathe through the mask. The air is pulled in from around the sides, leaving the wearer completely vulnerable to whatever is in the air. Kooding's response when asked about it was this,
"We are sorry to hear that you did not like the products. However, breathing around the side is normal in cotton masks with minimum air flow through the front and it does in fact protect from the virus. If you are looking for high level of protection we are soon launching KN95 masks which will allow better protection."
The mask they're selling doesn't work and when you complain, they won't let you return it and instead try to sell you something else. I regret not doing more research on this company before giving them my money.
