GE Grout Whitener, Pack of 1, White 1 Pen

The product was exactly what I wanted. My grout transformed from an original dull beige color to a beautiful bright white. The only problem was the tip wore down before I ran out of paint. I suggest an extra replacement tip be enclosed. Grout is rough and by the time I made it to the second tile wall in the kitchen the tip was no longer sharp but soft and fuzzy. The pen still worked but, it no longer made clean lines. The thick fuzzy tip made clean up on the second wall difficult. The color and appearance is awesome. I will use it again gun future remodel projects.
