Here is our UV Pen Light. This UV Light will fit in your shirt pocket, is lithium-powered, and is charged with a USB plug. Many of our customers are now using this as their primary resin-curing tool. It will cure the pit in about 10 seconds and pierces the tint of a windshield better than the sun which makes it great for curing under pressure! Also, if you have a star break with a leg that reappears when you take off the pressure, point this at it and it will freeze it right where you want it!
