Wild TiesMen's Green Microfiber Pi Symbol to the 50th Decimal Mathematics Math Nerd/Geek Novelty Tie Necktie

This is one of the best quality Pi ties I have found. Perfect for a Math lover. Suitable for a big and tall guys if you tie it right. My only complaint is that it only comes in Green.

Great tie but it is a bit short. The design and craftsmanship is excellent, however; due to how short it is it is hard to tie a double Windsor properly.

Well no one has called bull$#1# on me at work yet so it is at least somewhat presentable while being within the realm of individualistic. Would be a five if it was made of better material but also a lot more expensive so a decent trade-off.

I liked the tie. When my students asked me about it, that gave me a teachable moment to explain PI. But when I washed it, it was never the same. Make sure you dry clean it.

This tie is exactly as it is described! The color is not too dark, which is sometimes hard to judge from a picture. It truly is a perfect gift for anyone who loves math!

The Pi sy'mbol is very subtle and makes for a very cool and unusual tie. My husband's birthday is March 14 - pie day as he constantly reminds us. The tie will be worn on the birthday and every occasion he can think of. I also got him a Pi tie clasp too - he was pleased with his gifts.

I get compliments on this tie every time I wear it! I only wish it had more digits of Pi!

My brother teaches math at a university and seemed to really like this. It's somewhat subtle and has limited cheese factor, versus many of the other math-related ties I saw online.
