Review on 📏 Steelex M1085 3" Digital Micrometer by Mario Beaklini

The micrometer was sealed in a plastic box with cardboard around it to prevent opening. It was written on the cardboard sleeve with a pen. It turns out that the micrometer sat on the shelf for a long time because both batteries - mine and a spare battery - had sat down. I can't check the microphone until I put new batteries in it.
