## Questions & Answers

**Q: What color is the chalk ?**
A: This particular chalk is light violet. It is intended for very temporary marking, e.g. , it is designed to be removed with a strong breath of air; thus the name DUST-OFF. If you want marking chalk that is more
long lasting, use REGULAR or STANDARD, which comes in about six colors. DUST-OFF is very easy to remove, but this comes with the issue of being being VERY TEMPORARY and some what inconspicuous.

**Q: Can this be used in a tajima ultra fine chalk line**
A: The Dust-Off Marking Chalk is compatible with most brands.

**Q: Can this be used on fabrics/sewing as temporary marking?**
A: It is not recommended as the chalk will not be easily removable on fabric or sewing material.
