A great find............
I used to buy these items fro our local COSTCO, but they stopped carrying then.  When I went to Amazon and was supprised to find they were still available on-line, however I wondered if they were true replacements or not.  To my surprise they are, in fact, exact replicas of the brushes that I formerly bought from COSTCO, so my purchase was a 5-star event.
