Glass Beads
Glass beads are a mineral, iron-free reusable abrasive with a wide range of applications. Due to their (round) grain shape, they have a low abrasive effect and are therefore ideally suited for a gentle cleaning. Our customers appreciate the special ability of the glass beads to create a silky matte surface finish.
