I have a stash of N95's and other surgical masks - for use by hubby, I guess.
I don't go anywhere.
I'll hide a couple for me, for emergencies.
We could always use the oldie - but goodie.
Wonder what the reaction would be - if one just walked in wearing - a wooden peg. lol
With perhaps - swim goggles.
I like wearing the face mask when I'm out and about...it keeps my face warm in this cold weather we're having here lately.
I wear the surgical face mask.
You can buy them in a 10 pack for $8-12.
That's not me, btw...although very similar
