## Questions & Answers

**Q: Is the lid plastic?**
A: Yes, but the rest is stainless steel. Can't recommend this cup enough, it keeps drinks hot for hours and is really nice to drink from.

**Q: Can you put the straw through the lid?**
A: Yes, there is a slide opening, but not water tight when you use this option.

**Q: Does this fit in a car cup holder?**
A: Hi There, Thanks for reaching out to us. It will depend on the size of your cup holder. Please find the approximate 30oz BEAST measurements below, which can help you to determine if the tumbler will fit in your cup holder. Diameter :9.9 cm / 3.9 inchLength: 19.5 cm / 7.68 inchBottom diameter: 7.5 cm / 2.95 inch If you have any questions or concerns please do feel to get in touch with us directly,Have a great day, The Greens Steel Family :)

**Q: Could i put a fizzy drink in this?**
A: Wouldn’t recommend it. The lid barely copes with the pressure from the steam on a hot drink. A fizzy one may send it flying unless kept really still.
