📏 Precision Plastic Vernier Caliper: Ideal for Accurate Jewelry Measuring Review

These do what they promise. you will measure. However, they are EXTREMELY loose. You need to hold the slider with your thumb or forefinger and read the measurement while holding it against what you are measuring. As soon as you move them the least; the measurement is lost.

That "something more" poses a problem: you could measure something that is say 4.9mm and you could never get the fractional part since none of the lines would match. I really can't be displayed with calipers that are cheap enough that you could give them away as party favors, but

At first they didn't open past 131mm, but it was just a thin mold burr that stopped them; Pushing harder sheared that off, and this model opens to 157mm. From 120 mm, the mm lines become wider and somewhat blurred. The 1.6mm metal rod that extends from the end for measuring the depth of the holes is about 1mm short, although you could fix…
