I like looking really closely at paint imperfections to determine how to correct them. Is the chip through the clear coat or all the way to the metal? How about checking out upholstery defects (ink marks), rust areas, or removing that painful splinter in your hand? This versatile 10 time magnification loupe has a clear base that lets the light in, while the adjustable eyepiece allows you to set the focus according to your astigmatism. The lens may also be popped out and used without the base! Maximum versatility. 2 1/2" in diameter with a nice storage case included. Buy one for the house and one for the garage and see what you've been missing!
