Amicable Numbers pair of keyrings

Outstanding purchase for so many reasons!

I am incredibly impressed with the outstanding quality of the products I purchased from MathsGear, the variety of products that they sell, the speed of the delivery and with the interactions I had with employees from MathsGear. Highly recommended!

An Amicable Purchase

They're very nice. My boyfriend (who also happens to watch Numberphile from before I met him) and I have them on our keyrings and we both like them a lot.

They arrived just in time for Valentine's Day. My girlfriend really liked the gift of the 284 keyring. (I kept the 220.)
