## Questions & Answers

**Q: Is the 24oz small?**
A: It's about the size around of a 16 oz plastic bottle of soda, but taller.  It fits in my cup holder of my car.  Don't think the larger one would.  Since it keeps ice so well, I often refill it with water on the ice still in it.  I don't consider it small or large.  Like Goldilocks said, It's Just Right.

**Q: Do you sell the chug straw lid separately?**
A: I had ordered a couple different 24oz pictured with chug lids, but I received straw lids. What I have eventually purchased was a 24 oz with both lids, to make sure I got the Chug lid! So ask your questions to make sure you're getting the right product :-)

**Q: Can I purchase a replacement straw lid for the Thermoflask?**
A: Yes. I just went through this for the 40oz Thermoflasks I purchased at Costco. The straw lids are not sold by ThermoFlask directly (on their website) but it is sold by their manufacturer, Takeya, for $10. Www.takeyausa.com

**Q: Is the straw lid insulated?**
A: Good question! The leak-proof straw lid will keep your drinks cold for up to 24 hours and hot for up to 12. It is not insulated.

*by I***� on 2 April 2025*

Lo uso para cuando voy a correr y me resulta cómodo por su tamaño, de material resistente, a pesar del calor mantiene la temperatura fría sin importar el exterior. Una vez lo olvidé en pleno sol y llegué a pensar que el contenido estaba caliente sin embargo solo se calentó la Tapa por lo que el agua seguía intacta en temperatura. Puedes usarlo y también obsequiarlo a quien gustes, todo un lujo 🤩
