This is my second purchase of Mathematica face mask for my child. He stained his first mask so he asked for a second Mathematica face mask. He only wears BeauTies masks because he likes the designs and very comfortable to wear.

This mask is comfortable to wear and as a math person, I love the unique design!

Gave it as a gift to my husband who is an engineer. He loves it. Fits well. I have bought quite a few masks from Beau Ties and all have been very high quality. They hold up well when washed.
