### ⭐⭐⭐⭐⭐ Actually glows under blacklight

It's hard to find a marker that visibly glows under blacklight. This one worked well enough though Color quality: great

### ⭐⭐⭐⭐ Good UV marker
*by A***R on February 13, 2019*

This marker works well, but it does show up, without UV light, so be discrete in how you mark property, and they might not notice. The markings appear to be glossy, without UV light.
