My 10-year-old son chose the Silver Pi to 35 Decimals necklace to give his Mathletes coach as a thank-you gift for coaching his team this year. She was absolutely delighted to get it!

I received the 2 Pi necklaces sooner than expected. It is a gift for my son, and I hope he will like it as much, as I do. It looks just like the picture and is crafted very well.
