Did the work.

It's just like coloring with a Sharpie. Still looks great 4 months in.

Pleased

I did not notice much of a difference after using them.

Easy to use BUT the pen tip wears out fast

Before using make sure to follow instructions. Initially nib would be dry, you need to press against a hard surface, so that the nib goes in breaking the seal and the white paint fills up the nib and then you can start using it. Everytime you feel the nib is dry you need to repeat this step. 7ml is less and costly. Maybe better to buy a white paint and a small brush and repaint the Grout.

I went over some grout lines which now look so much better.

Old looking, discoloured grouts are white again. The pen is easy to use, compact (in fact, you might misplace it easily). Make sure the grout is clean, moudless and dry first. I cleaned it with some grout cleaner and the dried for a while as well as with a blow dryer to be sure. Just shake it, prime it by pushing it on some cardboard and then gently go over the grout, one even stroke. I did not really press, I coloured the grout and it came out clean, white with not leaks. The tip is not thick and the liquid flows nice and consistent. I couldn't believe it, after all the products I had tried, this one worked. It says to repeat after an hour, but my first pass was already fine. Amazing little product.

Great for making a tired rental bathroom into something worth bathing in! You don’t get a lot of paint in one pen, so had to buy three to do a whole bathroom which isn’t massive. Left hand side of the picture is touched up, right hand side is without the application. Noticeable difference so am satisfied.
