Review: Great transformation of my kitchen!!! - Great solution to a quick fix for an easy DIY!!! These grout pens are so easy to use and effectively changes your grout to the color of your dreams!!!! Such a huge difference with a little bit of effort!!!! My grout was very wide and porous so I needed 4 total pens to complete my kitchen. It was a bit awkward to use the pens constantly upright as opposed to a floor where gravity helps...but nevertheless they did the job!! They changed my VERY DARK GRAY grout to a bright white, I also needed a few passes to get the coverage I needed but it was a success! My kitchen now looks cleaner, brighter and much better than before!!! Buy them!!! Awesome price awesome outcome!!!
Review: EXCELLENT PRODUCT!!! - This pen was excellent. My black grout was faded. The pen was extremely easy to use, easy to wipe off. The nib just flowed along the grout lines with ease. No oder. I bought the double pack but didn't need the second pen. The whole thing was much fun and had such great results, I wish I had more to do!

## Features

- LOOK BRAND NEW: Skip scrubbing tiles and use GROUT PEN to paint and recolor your grout for a bright clean appearance
- USE ANYWHERE: Ideal for the bathroom, kitchen, and any other room that has floor or ceiling tiles.
- LONG LASTING INK: Tackle small or large DIY projects with a pen that covers up to 150 feet of thin 2mm grout
- ADVANCED FORMULA: Non-toxic, water-based colorant that covers grubby grout stains making it look brand new again
- CAP COLOR: Use the color chart (see images) for most accurate color depiction. Pen cap represents each pen's color but is not expected to be the exact shade, do a small test area first
- USE ON UNSEALED GROUT ONLY: GROUT PEN may not bond to sealed grout. Test grout with a few drops of water. If the grout does not absorb the water within a minute this means the grout is likely sealed.
- TIP MAY WEAR DOWN: Tip is made of cotton, pressing too hard will damage tip. Contact seller for replacement tips if needed
- SHAKE ONLY WITH CAP ON: Tip is removable and may fall out if shaken hard, only shake pen with cap on (note - Pen does not need to be shaken at all, instead gently pump tip to activate)
- DRY TIP: Pen needs to be primed before use, all new GROUT PENs come with a dry white tip. To activate rapidly pump the tip (30+ times) until fully saturated

### ⭐⭐⭐⭐ Great product at a great price!
*by L***Y on March 25, 2026*

These worked fantastic and left my bathroom looking refeshed and next to new! Leaving 4 starts because if they came with just one more tip each, I believe 1 pen would have went just a little farther. But you can flip the tips around and use both sides before swapping it out for a new one, too. Use a gentle hand with these and maybe you'll get more use than I did. 2 pens were enough to cover my entire bathtub, with some areas needing a second application.
