This is the perfect black light/uv flashlight to check your crystal collection or verify the authenticity of your amber. Plus the added convenience of a keychain so you will never lose it!
Squeeze to activate LED black light. Super teeny and light weight-about the size of a quarter. Batteries ARE included and replaceable: 2X CR2016 3.0V button cell
Bonus: Check for pet messes & identify fake currency!
Please note, darker tones of amber such as black cherry and cognac will have less fluorescence naturally.
