The pen is red brick brown and does not survive water.
The pen is not dark brown it is more like a red brick colour. My wife used it as a rental friendly way to add an accent colour to the kitchen wall but it does not withstand a damp wiping let alone scrubbing so not a good choice for toilets. We know we have to be careful when cleaning the wall but it is okay as we can scrub it off when we move out. The tip of the pen did not disintegrate for us like some other users mentioned and it is important to keep in mind that you need to wipe after every line you make. Overall for us it was not so bad considering our circumstances but for sure it is not the product it is marketed to be. For rental and aesthetic purposes only it is ok but it will not survive long in other cases.

Good quality grout pen -- but color is not as shown online
Good quality grout pen. The color is not what I expected, but it's not surprising because it's essentially impossible to match colors by looking at an image online. It's more orange than copper brown, which is what I wanted. None of the other grout pen brands have the color I want to buy.

Penna per coprire le imperfezioni delle mattonelle e per ravvivare le fughe
Il prodotto è molto valido, si applica con facilità e si asciuga subito... cosa molto importante, sopratutto per chi ha bambini ed animali in casa, è che si tratta di una tinta atossica... quella che ho preso io ècolor terracotta, guardando anche il colore del cappuccetto della penna, pensavo fosse di un marrone un po più scuro... comunque buon prodotto. Grazie.

An easy alternative to re-grouting
These pens really work! The dye hasn't faded or come off since I first applied them a year ago. That said, you do go through the ink/paint quite quickly, so you might need more pens that you think to complete the job. At least I did.
