what does the Bellow Bulb Duster weigh?
One answer to this question on your site is 5 kilos - but that is nearly 10 lbs.
I couldn't handle 10 lbs with one hand. Do you mean 5 oz?
When I first saw that 5 kilo weight I thought this duster was not for me.
The Bellow Bulb Duster weighs 7.5 oz. It is a very useful, light tool.
