Golden Mean Brow Measuring Calipers

Created right here in New Zealand and sold worldwide!
This unique tool is a game changer for brow design - it works on The Golden (phi) Ratio 1: 1.618 - which is considered in all things artistic to be the 'perfect' ratio.
It appears many times in geometry, art, architecture and is particularly useful for measuring eyebrow dimensions to achieve the best design for your customer.
