Review: Easy to use. True to colour. The grout in our bathroom was very dirty and discoloured. Needed a good deep clean, after a scrub and using this pen our bathroom looks brand new and sparkling! We have floor to wall tiles and I managed to do about 90% of the room before the pen ran out. Have purchased another! Very impressed :)
Review: Ha sido muy fácil usarlo y el resultado es muy bueno. Pedí el gris claro y quedó perfecto. Es lo estaba buscando.

## 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, so easy to use, literally just need to draw lines through the grout, that’s it and it’s done. No harsh chemical smell either. Regarding the colour, the chart shown is what the colour looks like on the paper but since grout is a different texture, therefore the actual colour would be lighter.
