## Questions & Answers

**Q: Can anyone show me a product on Amazon I can order to cut this with please?**
A: I did mine with just a utility razor blade but as Warren said a hacksaw might be good, so I think it might be too soft for that.

**Q: Is the logistics updated in time?**
A: No

**Q: do you have brown color?**
A: Mine is 1 3/4 inches and it’s a tight fit, I’d guess it will work

**Q: Will this scratch interior wood floors?**
A: The bottom is flexible and soft. I don’t think it would.
