Blue UV Reactive Water Dye

Amazing!

A little goes a long way! The glow was very noticeable and really made my project stand out!

Cool

Minus the first one getting crushed and opened. You sent me another one and all was well. Thanks for the quick response.

Blue UV Reactive Water Dye Works

I used the UV reactive water dye to test the effectiveness of a cleaning operation at work. I mixed the UV dye with some water, in order to spray the dye solution onto a plastic surface. The dye was non-staining to the plastic, was perfectly clear in normal daylight but turn a nice blue color under UV light. Excellent product, and would definitely purchase again.
