Bests & Worsts Reviews from Amazon

We just bought a house, and one of the biggest eyesores was the downstairs toilet area because the grout and tiles are so old and miscolored. I'm so glad I tried out these pens, it covered almost the entire bathroom floor (and probably could have colored more, but I was being fairly careless and was wiping up large areas of paint when wiping off tiles). Unfortunately, after a week the coloring seemed to go away some. I am not sure if the pain 'soaked in' to the grout or if we were just too quick to put the rugs back over top. Overall, though, it looks marvelous! Up close, it's a little iffy looking but what guest is going to be that close to really notice? *Update: we went to Lowes and bought some of their grout pens when these started to run out. Theirs had a harder/wider tip, which got more paint on the tile, but overall seemed to cover better.*
