This is our 5Kg (50 towerbusters) easy link.
One piece is enough to disable the DOR emission of a small/medium tower so you have plenty to reverse the effects of a large area.
1) CAMO COLORS: Light Siena Brown, Green, Dark Chocolate Brown To hide them better, specially if you throw them in the field.
2) SAND & CLEAN for Smooth edges, softer feel and better throw ;-d (it is time consuming and laborous to do this with great quantities so we must charge for it)
WEIGHT: They weight a little over 3oz- 100gr
