This is a set of four wooden coasters, engraved with mathematical symbols and their values. This is a perfect gift for anyone who loves math! A great conversation starter - while most people are familiar with the concept of π, the other symbols are less widely known.

The symbols included are 'e' (Euler's number), π, ϕ (golden ratio) and 'i' (square root of -1); each symbol is included once in the set.  

Walnut wood is beautiful, making these very elegant, yet practical objects, protecting your table from moisture and heat. Suitable for both hot and cold drinks, these make perfect drinks, beer and coffee coasters.

  • 3.6" x 3.6", and around 0.2" thick
