## Questions & Answers

**Q: What scales are**
A: It tells you in the title

**Q: Are the measurements indented in the ruler or are they just printed that will wear off after a month or two**
A: Thanks for your question.  They are printed on the surface, but we have not had any issues with the scales rubbing off at all.  I hope that helps.
