This is a reusable fitted style mask with two layers of cotton fabric. The lining fabric is a print of actual Rat footprints. And due to the fabric pattern the placement of the ratties can differ slightly from the image shown - but not by much. And yes, the design is of a naked rattie. :-)
 
It is pocketed to be able to use a filter. Can be used without one too.
 
Comes with Elastic.
 
Fits - Adults
 
All of this is cotton, except for the elastic, and can be washed in hot water. Please wash in a delicates netted bag to keep it from wrapping around other laundry items.
