Pi Ring - Math Gift - Pi Day - Adjustable Aluminum Ring
This "Pi" aluminum ring is stamped by hand, one letter at a time on a 1/4" wide blank and shaped to fit your size. This ring will display the numbers of Pi to approximately the 18th digit, depending on the size of the ring you buy. Small rings will obviously fit less digits, larger rings more. Makes a great gift for the math lover in you life!
Please avoid contact with water to keep the black in the lettering and designs from fading.
Our rings are made out of Pure 1100 Aluminum, which is food safe and does not tarnish. They contain no Zinc or Magnesium which are often found in common aluminum and can cause skin reactions. This also means it doesn't contain the properties of other metals that might tarnish and/or turn your skin green.
Please note that due to the nature of hand stamping, every item varies slightly from the photo.
