Does one contain more product or does it have a bigger tip?** A: The Large Pen is 15mm wide (about the size of a typical Jumbo Marker). The 5mm pen is about the size of a regular sharpie marker. **Q: What size room does one pen cover?** A: Good question. The manufacturer states "up to 60 meters coverage for narrow grout joints". 60 meters is approximately 196 linear feet, however results vary as the porosity of grouts can very greatly. **Q: Will this pen let me change the color of grout that is currently white but discolored? I want grey grout lines on my bathroom floor.** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***R on 13 February 2017* the grout in my kitchen floor tiles had got very discoloured over the years and I was deciding if I should get them replaced but thought I would give the grout pen a try first,am I glad I did after just one cost the floor looks like new, I am so pleased I have ordered more to do the bathroom and cloakroom, it is so easy to use and goes a long way.
