It was the perfect touch to my Ali day outfit, and it’ll look great all year long too

I love this necklace. It is so pretty, and I love that it looks like a classic piece from far away, but shares my love of math up close.

Cynthia Berry
My wife teaches math, she likes the necklace

Sandra Foster
This is a good item for signaling that I'm polyamorous to those who know the symbols, on the street people just think it's a math thing.

Howard Phillips
Even more beautiful in person. This was a gift to a math teacher. She likes it so much because she can wear this with any outfits!

Kaitlyn Ho
Very cheap material. Broke after only a few days and left me with a rash.

Maybe I didn’t read the details, but the necklace was much longer than I expected. I specifically bought it because of the pi symbol. Since the chain is so long, the pi symbol is so low or hidden by clothing that no one would see it. I like the idea of how it’s threaded through the infinity symbol, but again the pi isn’t visible when I wear normal clothing because I don’t really like long long necklaces. I suppose I don’t know how it would slip over my head if it were shorter, but still...
