100mm Dual-Scale Brass Pocket Caliper

This set contains two identical brass vernier calipers, each measuring 117 mm (4.6 inches) in total length with a functional range of 100 mm. Constructed from solid brass with copper surface treatment, they provide non-magnetic performance and resistance to corrosion and physical distortion. Equipped with dual-scale markings (mm and inch), they support fast, accurate readings for inside/outside diameters, depth, and step measurements — especially suited to beads, rings, and fine jewellery components. Compact and robust, they are designed for professionals and hobbyists who require dependable precision on the move.
