## Questions & Answers

**Q: Can this be used in making precision markings or is it more for rough cut applications?**
A: I do not feel this is to be considered a precision instrument.  There are small bulges (drips), of paint along various edges that prevent one from being able to accurately draw straight lines or check an item for “square”.

**Q: How thick is this ruler?**
A: The Mr. Pen ruler is about 1/16" inch thick and is made of a good quality metal.  The metal is hard to bend and I personally like it.

**Q: Will this work at a Tshirt vinyl ruler?**
A: I'm not sure I understand your question.

**Q: Is this ruler 1.5" wide?**
A: The top portion is about 1.25 (the "top of the T") the longer part is 1.75" wide. Hope this helps
