Review on Efficient Replacement Head for Fuller Brush Tile Grout E-Z Scrubber - Perfect for Cleaning Kitchen, Shower, Tub & Tile - Purple by Libby Walker

I first bought a Fuller grout brush which came with a handle. The brush head did not fit the handle that came with it. I returned this set and just ordered the nozzle to use with the pen I already have. When I received this brush it came in a padded envelope with no packaging whatsoever. There were these faded bar codes - one on top of the other as shown in the photos. Setae were missing in two different places. I'm not sure if it's actually a fuller brush. To return.
