These color-changing Polymer beads are the Fleur-de-Lis design. Mirage beads are a lightweight hollow-form Polymer beads that each measure 15mm by 23mm. This is a 9.5 inch strand of ten four-sided, oval beads.
Mirage Beads are thermo-sensitive and continuously change color, ranging from black (when cool) through all the hues of the rainbow as they warm.
Although Polymer beads are very durable, it doesn't seem like a good idea to submerge in water.
