Announcing our new TUFFLEYETM PEN LIGHT with the same safe visible blue curing capability of the larger AC/DC light. This new light runs on 3 AAA batteries and clips in your shirt pocket. Great for the fishing trip and as a light to cure Tuffleye products. This light has come from the request of many of the Tuffleye users for a smaller more convenient and more economical light. It has taken several years of design and engineering to produce this very high quality pen light. Possibly the last pen light you will ever need to purchase. This little light can illuminate an entire room. Remember, visible blue light will not “night blind” your eyes to the dark like white light will.
