## Questions & Answers

**Q: What is the exact size of each bottle?**
A: dia 1.93 inches, height 4.45 inches, neck finish 22-400

**Q: what is the largest label these bottles can take without any distortion in the label?**
A: the max size of the label is 6 inches in length x 2.5 inches in height.

**Q: Will liquid drip down side of bottle after pouring?**
A: I have used these for homemade vanilla and have the neck of the bottle wrapped in string which is stained from drips, so I would have to answer yes to this question. The string keeps it from dripping down the bottle, so you could start a new fad :-)

**Q: Are these food grade?**
A: this is pharm grade, much higher level than food grade.
