Thermos Nissan 12-Ounce Stainless-Steel Tea Tumbler with Infuser

Most problems with mugs I have tried in the past are solved in this product. This mug comes with a tight sealing lid so that you can put this mug with hot drink in a brief case upside down and run to a subway station. No spilling, and this product is better than a plain Saran Wrap solution. The sipping lid has a deeply recessed bottom where you have a hole for liquid to come out. That is, the spill risk is very low even in pitching and rolling Boston's subway. So, you rarely need to use the sealing lid unless you want to brew tea in it or put the mug in a backpack. (See the other review to learn how to brew tea in it.) Also because of this deeply recessed sipping lid, this mug is easier to use spill-free while laying on a sofa or maybe even on a bed with a high pillow!

Lack of handle presents little inconvenience at any situation I've used this mug. A both handed person like myself needs not worry which way to put the mug, which way to put the sipping lid, and which hand...Read more

This is a great product- leak proof with amazing heat/cold retention. For tea drinkers, I just thought I'd add a better description of how the tea lid works. It is actually not a strainer for leaving the tea leaves in the cup (the tea would be so bitter!), but an ingenious way of brewing tea! You put hot water in the cup, then screw on the strainer, add the loose tea leaves, screw the top lid on, and turn the cup upside down for a quick brew! (Since it is leak-proof, you actually can turn the cup upside down easily) After brewing, you just turn it right side up and replace the strainer holding the spent leaves with the sipping lid, and voila- a quick and pretty decent cup of tea! Highly recommended.

This is how you brew tea:
(1) Remove outer cap and tea filter.
(2) Check all gaskets are properly seated.
(3) Twist tea filter onto the cup to seat tightly. Put tea leaves in the tea filter. Be sure the tea filter is seated correctly. You can also put tea leaves directly into your cup if that is your preference.
(4) Pour hot water up to middle of filter. Over fill may scald.
(5) Properly seal the outer cap tightly to prevent leaking when used for travel. Turn upside down for quick brew.
(6) Remove outer cap and tea filter after brewing and replace with slipping lid.

For Best Results

For maximum insulation efficiency: preheat or precool your cup just prior to use, fill with hot or cold tap water, let stand for 5 to 10 minutes and empty.

Note that it comes with 3 lids: (1) Outer Cap (2) Tea Filter and (3) Sipping Lid.
