badger paint bottles

If it has the same cap as most other Badger and Thayer and Chandler brushes, Tamiya paint bottles should screw right onto it. You'll have to shorten the tube a little though. I carefully (carefully being the important word!) heated the tube on mine with a heat gun and bent it so it aims right at the bottom corner of the bottle and then trimmed it so that it barely clears the bottom. That way I can pull just about all the paint out of the bottle.
