  • Available as loose beads (5 kilo drum), or as sachets of beads (500gm), sachets measure 350 x 150 x 20 mm.
  • Place around the perimeter of the case, or in a drawer. Use 1 sachet or 500g of beads per 0.7 cubic metres, more may be required for dependent upon design of display case (multiply cubic feet by 0.02832 to get cubic metres).
