My father in law keeps his bulk 22 ammo in on of these Koolaid or Country Time Lemonade cans which I thought was pretty nifty. My ammo smells a little grapey, but hasn't corroded or anything.
This brush I found today in the Fabrics/Crafts section at Wal-Mart. I have been looking for a replacement for the "lens pen" that I bought from somewhere. The lens pen was a neat idea, but the polishing pad thing was just an accident waiting to happen.
The brush is natural bristles and was only $2. It has a flat cut to the end of the brush instead of a taper. It brushed the dust and lint off of my scopes fairly well, if the bristles were a little longer then they would be perfect.
