Frienda 5 Pcs Eyebrow Measuring Caliper Tool Microblading, Bright Colors

Great for its intended purpose. Slides a bit too easy. I suggest rubber bands, or gluing a silk ribbon to the slide surface to slow its movement.

I've used these for years. For the price you just can't beat them. I have one in my desk, and other tool boxes. They are way more accurate than you think they'd be. I use mine daily

Good quality and accuracy value for the money

Cheap plastic calipers perfectly suitable for measuring eyebrows, I imagine. The sliding mechanism is a little too slippy, but for $1.50 in plastic, I shouldn't expect much. But these things are clearly an attempt at Vernier calipers; let's talk about that. The Vernier caliper is a high-precision measuring device that's been around for almost 400 years now; it lets you obtain highly accurate measurements by comparing the normal scale (sixteenth inches or mm) against a different scale that's just a little different, and seeing where the two scales line up. These eyebrow rulers have those extra scales on them; they're clearly intended to be Vernier calipers. Problem is, they're low quality as Vernier calipers go. The "zero" is off by a fraction of a millimeter, which is to be expected; these are cheap plastic, not the product of German engineering. But the measuring bar (the rod that sticks out the end) is visibly poking out by a millimeter or two. That's no good. I guess that's reparable by using a Dremel to sand it down so it's flush, but one shouldn't have to. Real talk, if you want a super cheap Vernier caliper, Harbor Freight sells one for $1.99, made by Pittsburgh ("6 inch utility caliper"). They're very good calipers for the price.

Good price

Bought these to have lying around for occasional use to validate stuff I think I know like, “is that a 5/16 bolt or 3/8” or “is that 3/8” tubing” and for that they are fine. Otherwise: - the markings are off about 1/16”, - all but 2 of the sliders are so loose as to be annoying and barely usable, - only one slider has enough friction . They aren’t accurate enough to make any sense using the vernier scale and there are no directions if you don’t know how to use the vernier. But for the money…..
