These "prime" set of 7 math symbol coasters are great for a end of year teacher gift for your favorite math teacher. Custom cut from acrylic and engraved with 7 different math symbols, this set of 7 coasters is sure to inspire the solution to at least keeping rings from getting on the table. Each coaster is 3.75" across and cut from quarter inch clear premium Plexiglas. We are now including the integral sign in addition to those shown in the photos because you can't have a prime set with just 6 ;)

This item is on closeout so once these sets are gone- they will be sold out!
