## Questions & Answers

**Q: Will these work on 16oz bottles?**
A: Yes, as long as the spout of the bottle has measurements which are slightly less than the seal. I use mine for 4 and 8 inch bottles. They work really well for our products which are oil based.

**Q: Will these fit a 4oz jar?**
A: From the ones I've ordered  definitely not. They only fit like 10 gram containers
