DaemsonDaemson Mini UV LED Keychain Flashlight, Compact 395nm UV Blacklight, Portable Pocket UV Flashlight for Detecting Stains, Scorpions, and Fluorescent Elements - 6 Pack

Small, good keychain, works well, light is bright. Good stocking stuffer

these are great, i've been taking them camping and they are really lightweight and sufficiently bright. they die pretty fast though, in general i'm replacing them after just a few days of casual use. seems like maybe it's when they get wet, the switch just starts to go and they get really dim.other than that though these are nice

Easy to have on your keychain or in a small purse. Excellent customer service. Everyone wants one albeit the blue or purple ones.

These mini lights can help you find your way in dark wings, or check your script backstage.

I got these to walk to my hunting spot before daylight without spooking game. They aren’t bright. But give you enough light to not trip over stuff.

These provide a bright light but only 5 worked and one of those was iffy. The slide switch is an improvement over those that must be continually pressed to remain lit. Enough force is required to move the switch that I'm not concerned about it being turned on accidentally. They are very lightweight, thereby not adding much weight to the key ring. If all had been functional, I would have given these 5 stars, but given how inexpensive they were, five (or maybe four after a couple of uses) was still worth the investment.

These lights are not very bright at all.

Some key lights you have to hold the button down but these have a switch so you don't have to keep your finger on it to keep it on.
