## Questions & Answers

**Q: Does this cap come with the straw?**
A: No, and I would not recommend this product either. It leaks. Not fit for purpose.

**Q: Will this lid fit a one green bottle or klean kanteen flask?**
A: I don't know. I suspect they are brand specific so would need a Klean Kanteen lid for one of their flasks
