NADAMOO Grout Renew Pen White – 2x 20ml Pens, Replacement Nibs, Tile Gap Touch Up Kit

Overview

The NADAMOO Grout Renew Pen White is a practical two pen kit designed for quick touch ups along tile grout lines. Each pen holds 20 ml of ink and is paired with a soft nib that supports smooth, steady application for narrow gaps. The kit is sized for comfortable handling and is suitable for both walls and floors, helping grout lines look cleaner and more refreshed without major renovation.

What makes this set versatile is the inclusion of two nib replacements and a foldable cleaning brush. The pens are designed to deliver consistent coverage, with up to about 400 meters of line achievable on typical 2 mm grout gaps. The compact pen dimensions (roughly 25 mm diameter and 135 mm length) balance control and reach, making it easy to work along kitchen backsplashes, shower walls, and bathroom floors.

What you get

• 2 white grout renew pens, each 20 g (approx 0.7 oz), capable of up to 400 meters on 2 mm gaps
• 2 nib replacements for continued use without buying new pens
• 1 foldable cleaning brush to quickly loosen surface dirt and prep grout

How it works

Apply the ink along the grout line with a steady, controlled motion. The soft nib helps maintain a smooth flow, while the bright white color creates a crisp contrast against tile, contributing to a cleaner overall appearance in kitchens, bathrooms, and entryways. The design supports both wall and floor applications, so you can refresh multiple areas with a single kit.

In practice, this kit aims to refresh dull grout and restore a neater visual rhythm between tiles, offering a practical option for routine maintenance and occasional refresh projects.

Real-world use cases

• Kitchen tile lines around sinks and backsplashes for a cleaner look
• Bathroom showers and tub surrounds where grout color can seem worn
• Floor grout in entryways or high-traffic areas needing a quick upgrade

Tips for best results

• Clean and dry grout thoroughly before applying
• Test color on a small section to confirm the shade matches your tile
• Store nibs and pens in a cool, dry place to prevent drying out
