Perfect colour!
That's the perfect colour for my wooden effect tiles. Very easy to apply!

Great product
I bought two of these. The colours I bought were what I expected and the pens are great - easy to use and apply smoothly. Great idea!

Great finish but she wants another colour!
I was very impressed with the result but she doesn't like the dark brown colour. It means that I'll be buying another colour for a re-run in the near future.

Worked a treat
Does what it says. Completely transformed my newly laid immitation walnut tiles after the tiler used the wrong colour grout (light grey instead of dark) and made the spacings too wide, completely ignoring our wishes, which had the effect more of a brick wall on the floor instead of the intended floorboards effect.... But the Grout Pen came to the rescue, and now the tiles look great. The spaces between have been minimised by the brown on top of the light grey, to look like small crevices by the brown, and the overall colour is more uniform - nothing like brickwork any more! I have had lots of compliments about my 'wooden' flooring from first time visitors, who know nothing about the tiles, so I know the effect is great.

The brown is a slightly reddy brown but this was perfect for us as it matched with the dark wood effect floor tiles, gives a good finish and is easy to apply

Good stuff
This product does exactly what it says it does, and has much improved the look of my kitchen floor. Started off with the small version and, as it proved successful, then went on to order the larger pen. This was even better, as the larger nib meant it went on quicker. Am happy to recommend this product.

Genial. Lo recomiendo
Esto es un restaurador de juntas... no sirve para cambiar de color una junta. Sirve para restablecer el color original.

Great Product
I bought the Large Brown Grout Pen. I was very pleased. It came promptly and there wasn't any leakage. I have large grout at my entry way and this size of pen work good. The brown has a reddish under tones which work great for me. I cleaned and wiped dry the tile and grout. I started in the far corner and worked my way backwards toward my hall. I wiped the marker left to right and then quickly went right to left to coat all the grout. I used my bare finger ( gloves were too awkward) to push the color in the grout, especially in the corners. I used dry paper towels to quickly wipe excess off the tiles. I used the damp cloth right after that. You have a few minutes to wipe up excess - not long. I waited about 24 hours to put a sealer over the tiles and grout. it's been over 48 hours and I Love the color and the improved grout. Clean up was easy. I threw the damp cloth away. I only washed my hands one time thoroughly and my hands came clean. I plan and getting the Dark Grey to do my bathroom. I would buy this product again. If I have any problems, I'll try and update. Update 6/23/2019 I'm very pleased in the way the grout looks today. I don't think it's faded or changed colors. I recommend this product and would buy it again.

Amazing solution!!!
I read the reviews on this pen before ordering and I also looked at another brand of grout pen before ordering this one. I have 1/4 inch grout in a bathroom, which is a pretty thick grout line. I ordered the white pen because of the thick grout and it was a perfect choice! In my photo, you can see most of the bathroom. Around the corner to the left is a closet and small toilet area which has less tile than what is seen in the photo. I ordered two wide grout pens and I still have some paint left in the second pan for touchups if necessary. I hope that gives you an idea of how much grout you can paint with two wide, grout pens. I completely recommend this product! It is a very, easy and affordable solution to changing the color of your grout! I really love the way it turned out.

Eine gute Sache.
Finde es gut, daß es auch einmal eine andere Farbe gibt. Ansich ist die Ware wirklich gut, leider nichts für einen dunkelbraunen Boden oder es ist halt Geschmackssache.
