The same box that comes with the coaster is perfect for Zentangle® tiles and other art supplies. The box measures 4.5" x 4.5" x 1.5".
 
Choose from three designs: "Well", "Paradox", or "Nzepple". 
 
The popular Zentangle® pattern “Well” is a design of swirls on a grid; a favorite in the world of Zentangle® artists.
 
A mandala-like design of the Zentangle® pattern “Paradox” features the same triangular pattern dancing around a circle to serendipitously form a star.
 
The gridded Zentangle® pattern “Nzeppl" seems to balloon like a zeppelin airship.
