This listing is for a 40 pound box of #4 Mil spec glass beads. Large

  High quality mil spec. glass beads. (not crushed glass abrasive)


 GLASS BEAD is an excellent media to provide 
smooth bright, contamination-free finishes. 
The round glass bead particles close up 
surface roughness and porosity.
This helps prevent corrosion, resists rust, staining, and fingerprints, 
and provides a bright, satin finished new surface.

GLASS BEAD will not leave any undesirable or ferrous residue impregnation on nonferrous blasted surfaces. 
Uncontaminated spent media is environmentally harmless.
