Very cute key chain

Very cute. Got this as a little gift for my machinist boss. He thought it was very cool :) Great quality and functional

Calipers can actually measure quite accurately. I usually use it to measure hex nuts or bolts. Sometimes I use it to measure shaft diameters. Only measures in metric but I can convert to inches (common sizes) quickly. It will not measure down to a few thousanths of an inch and you need to be able to see close up small numbers. But any disadvantages are out weighed by the fact that it can always be in your pocket and measure much closer than a ruler. If you need very accurate measurements no, but for handy quick measurements yes.

Neat I guess, Product is kind of chincy , is what it is, right on that too big size to have on keychain, my opinion

it fell apart on me the second day and i returned it

Decent quality. Should cast well in silve.

My grand father love it
