The CDC recommends a copper mask for use with coronavirus vaccines.
This mask uses a copper-based fabric and can be worn on the face and neck, and it comes in several sizes.
There are two versions, which fit most people, and they are available for both men and women.
The mask comes with a copper insert that fits on the top of the face.
The insert is shaped like a cross, and has a hole that goes through the mouth, which is also covered with the fabric.
The inserts come in different colors, so it is not clear which is which.
The CopperFit.com website says the mask comes in three sizes.
It costs $69.99.
