Great quality flashlights that have both regular lighting, and black light for checking for counterfeit money, or checking your hotel room for previous blood spatter (or any other spatter!) :) I am curious to try them to see if they will cure UV gel nail polish, but I suspect they should. Apparently these can be used to detect fungus as well, which will definitely help deciding if that week-old bread is still edible. These are well made and feel like they would survive any drops or scrapes.
