I recently got the COSOOS 2 UV Black Light Flashlight 2-pack, and I’m really impressed with their performance and convenience. These mini pen lights are compact and lightweight, making them incredibly easy to carry around—especially with the handy clip that lets me attach them to my pocket or bag.The 395nm UV light is bright and effective for detecting pet stains, authenticating documents, and spotting hidden markings or bed bugs. Despite their small size, these flashlights pack a powerful ultraviolet glow that doesn’t disappoint.They’re also waterproof, which adds durability and versatility for outdoor use, or if you happen to drop them in damp spots. Battery life is solid, lasting through multiple uses without needing frequent replacements.Overall, the COSOOS UV Flashlights provide excellent value, combining portability with strong UV detection capabilities. The two-pack is perfect for sharing or having a backup on hand. I highly recommend these for anyone needing a reliable, compact UV flashlight.

Works great! I bought this to identify uranium glass at estate sales. It is a slim design and fits perfectly in my cross body bag. You could put this in your pocket.

If you think you have cleaned a Kitchen / Bathroom surface adequatelyshine these lights on a surface in a darkened room.

I had an older dog that would vomit under the beds. I could never be sure that I got everything cleaned up since it was hard to see. I recently moved all the furniture and wanted to make sure the carpets were clean, so I ordered these blacklights. Not only did I find what I had missed cleaning, but I found other suspicious areas that allowed me to steam clean thoroughly. Highly recommend!

Wayyyyyy toooo much fun!!! I’ve been missing out for too long. Now I am black lighting everything. Fabulous.

A real good value.

Amazing product
