For sale is a Visible Dust Arctic Butterfly 724 charged sensor cleaning brush.
This is excellent for removing loose dust particles from camera sensors, inside refractors, etc.
Spinning the brush head for ~10 secs gives it a static charge for easy removal of dust particles.
This was great for when I used Canon and Nikon DSLRs.
Helps to minimise inevitable "dust doughnuts" arising from sensor dust.
