## Questions & Answers

**Q: Does the glass on the outside get hot if you have hot tea inside? I have a Teavana tumbler similar to this and it gets too hot for me to carry.**
A: I have the Aquaovo version of this tumbler and I found that as long as you don't fill it to the top where the inner and outer glass are fused, it doesn't get too hot. It's still warmer to the touch than a stainless steel thermos but it's not uncomfortable. Just don't fill above the filter level.

**Q: I want to know the size of this 18 oz glass tea tumbler, thanks.**
A: 7.5 tall 2.75 wide its a big glass it holds alot of tea. Its also my favorite tea travel mug I use it everyday well worth the money the glass is very thick. Its better then the teavana ones their glass is not thick. I woud replace it if it broke. Well worth the money.

**Q: does it have a non spill drinkable lid**
A: You can order a flip top lid from sunstea.com for $3.99 plus shipping.  I don't know why they don't offer it with this product from the start. The flip top lid has a sort of tube or spout that you drink from. There is no second air hole to eliminate the vacuum effect, so drinking from it is awkward. I would have been better off sticking with my old system of a Thermos travel mug and a long handled tea ball infuser.

**Q: where should i put the tea leafs**
A: I tend to put my loose leaf tea in the provided metal basket/shelf which rests on a ledge towards the top of the jar. That lets me pull out the basket to stop the steep.  Some folks like to put their tea at the bottom and drink through the basket (which acts as a strainer) but to do this you have to use something that can effectively steep indefinitely (for instance, some herbals become stronger but no less pleasant the more you steep them)
