Our skin responds to UV radiation by tanning or as sunburn. Damage may result in the form of wrinkles or skin cancer. A safer way to detect UV is to use these UV beads. They change colour when exposed to UV and revert to their original white state when removed from the UV. They can be reused many times and are an excellent resource for testing sunscreens, radiation penetration or for making bracelets etc. You can dream exciting applications! Price is for a pack of 100. Enquire about pricing for larger or smaller quantities.

Colour: Red, Light Blue, Yellow, Dark Purple, Violet, Maroon and Ochre.
