These calipers are identical to the small (120mm long) calipers, but have a 4th arm which bisects the smaller of the two ratios.

A couple of people asked me to make these – they’re useful for eyebrow measurements.

They come with a little laser-cut, magnet-equipped case. The dark hardboard ones come as standard, but other options are available as well.

For an extra $10 I can put your logo on the case – if you send me a file, I’ll send back a mockup image.

If you have any questions – feel free to get in touch. Nick Taylor
