Twin Pack (DARK GREY) Grout Pen - Designed for restoring tile grout in bathrooms & kitchens

Does exactly what it was intended for. Waterproof, easy to use.

It does a good job but you have to made sure your floors are spotlessly clean or it’ll pick up every little bit of dust and the pen becomes quickly unusable. I struggled at times to keep the amount of product coming out even but it looked great in the end.

Easy to use, very shiny when first applied but becomes more matt when dry

Goes on well but when your trying to tidy up it all comes out I definitely recommend leaving it a good 2hs before wiping off els your back to square one... filling it again with the pen... and letting it dry... easy flow and no horrible smell... they really should do a waterproof one as well as this ain't... don't recommend for bathrooms

Did just the job! Redo all the grout though for an even finish, not just concentrated areas. Looks like I completely regrouped my kitchen floor!

Was sceptical but very impressed..easy to use, good covering used in shower area and doesn't wash off.

I really enjoyed going over the grout on the downstairs loo and kitchen floor with this, so satisfying for it all the be the same colour again and looks new! Only thing is this has a slightly blueish tint to it, so didn't match the dark grey grout on the walls in the loo. Otherwise really good. Both pens were enough to do both jobs

This is really good. I had already regrouted in dark grey grout but it was a little patchy so I went over it all with this. The nib is just a bit too wide which causes a bit of an overlap but once that's been cleaned off (or if you have wider grout lines; mine are quite narrow) it's all good
