Roll-On Applicator Ball

The ball on its own, in six diameters and two materials, for brands running their own housings and filling lines. We buy to a tight sphericity and surface finish tolerance, because both decide how evenly product transfers and how much drag the user feels on the skin.

Sizes: 8.5–25.4mm
Materials: PP / glass
