Product Details
Grow sparkling, colored crystals overnight from a safe solution of potassium aluminum sulfate.

These kits include all the materials and tools you need to grow a single crystal, as well as a small hexagonal storage box in which to keep your crystal safe. This mystery crystal will be either blue, pink, green, or yellow.
