COSOOS2 UV Black Light Flashlight, 2 Pack 395nm Mini Pen Light with Clip, Waterproof Ultraviolet Flashlight for Leak, Pet Urine, Scorpion, Hotel Inspection, Dry Stain and Bed Bug.

These little things do wonders. They are both amazing and evil at the same time. They find every spot you missed. As far as the battery life goes I would invest in some rechargeable batteries from Walmart or wherever you choose to get them from. Your battery life depends on the brand you get. They will save you money in the long run. This flash light fits perfectly in your pocket and takes up as much space as a sharpee. As far as the design goes it holds up against accidental drops. Overall it’s a good flashlight, and a decent investment. You find yourself using it a lot more often then you realize.

Bought this portable Black light for traveling.you can check how clean your room really is from any stains on the sheets ,bed cover floor ,especially the bathroom….i changed room once because there were stains on the bed sheets and looked as if they didn’t change the sheets on the other bed …….,then you can see how clean the bathroom really is ,another time I checked the bathroom mirror and it was all loaded with small specks which looked like people flossed in front of the mirror you couldn’t see it until you turned off the light to check ,,had front desk send someone up to clean the mirror ,usually I try to do this upon checking in .just close the curtain using the black out curtain also so room is dark you’ll be amazed what you see…

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 well but if used frequently and often buy rechargable batteries as they drain down fairly quick

I love it takes very little time to cure and I can use it anywhere I am and perfect for small projects n spot curing

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.

Great size and very bright. Love them

Exceeds my expectations works well
