## Questions & Answers

**Q: What is the width of the plastic caps?**
A: 28mm, or about an inch and 1/8th

**Q: will these fit spice jars?**
A: Don't know if these will fit your spice jars - it depends on the size of the jar.  The answer above, however, is definitely wrong.  These are NOT "wine bottle size".  They are the same size and thread as a standard plastic soda bottle.  If a soda bottle cap will fit, these are nicer looking and more permanent.  If a soda bottle cap won't fit, look for a different size.
