Arithmetic Adult Face Mask

Arithmetic Adult Face Mask. Numbers, equations, rulers, all in a sophisticated, monochromatic design. Great for educators! 2 layers reversible, woven cotton 1 layer non woven filter built in (washes with mask) Stretchy cotton ties (adjustable, compatible with blue tooth devices and hearing aids) Proceeds make it possible for me to continue sewing/donating face masks, to those on the frontline of the pandemic. I’ve already donated more face masks than I’m selling.
