As others here have said, Ca dusters are not what they used to be.  Wood handle or plastic, the main problem is how few threads there now are in the standard size.  I bought this big one to try to compensate for that and seem to be successful.  It is big and hard to sweep nicely across one's car.  I may shorten the handle.  I'd rather simply have the old, smaller one with the one side packed with dense strings.  Yes, this did arrive with to much oil/wax but that is good in the long run.  Mine is wrapped in news paper to absorb a bit of it.
