Question: How to use it.  There is no instructions at all in the cup
Document: Yet if you are buying it with the main purpose of  using the strainer  I would shy away from it, unless some one else has shared how to use it properly. I would buy this again at the sale price. Probably not at the regular price considering the strainer issue and no instructions.
If you want crystal clear tea with no suspensions then you will need to use a filter paper under the strainer.Instructions - No care and use instructions included. Since it says its borosilicate glass, I presume its dishwasher safe.Received a coupon code for direct website purchase.
So far I am very pleased with the glass tumbler. I am writing this review to comply with the rebate. I was expecting how to use instructions inside the box, but there were none. I too thought the tea was inserted between the strainer and the lid and not in the glass itself. The lid with the inner seal is quite secure and keeps any liquid from spilling out. It was easy to use and did keep the tea hot for quite a while.
I just received my cup last weekend. The cup is nice and sturdy but feels a little heavy compare to the other double wall glasses i have. The steeping part is a little shallow in my opinion and unfortunately, you cannot really drink from it while driving it in the car (although it says Travel Mug). For me, it's perfect to use in the office though.
First off, it looks great. Functionally, it keeps my tea warm for quite a while and does not let any leaves up through the filter. The filter basket is removable if you choose to steep a regular tea bag and still want to use your glass tumbler. Paired with a flowering tea, it can be quite the conversation piece. Overall great cup at a pretty good price too.
I have seen similar Tea Mugs in Teavana, but didn't purchase one because they were so expensive. I thought I would try this one for half the price and it was definitely worth it. It seems a little fragile, so I would probably only use it at the office or at home. It doesn't appear that you can actually brew your tea in the cup because the strainer doesnt drop far enough into the liquid. It would work well to brew your blooming teas in.
Nice double walled glass tea tumbler. It arrived nicely packaged but no instructions on care was included. I liked the weight of the glass and tested the seal and it worked well. As another review stated, it would hard to steep tea without it getting too dark to be able to drink, but overall, it is a nice product. I would recommend this product to anyone.
like the concept but it is not durable at all. The inside glass just fell off and leaked out  within one week.I was using the cup gently
I have been using this tea cup for a month now and I am satisfied of the quality of glass and its double layer design. The only problem, as it mentioned by another customer, is that they can make the tea leaf more easiler to removable. But overall this is a great tea cup.
The item ships in a plain brown box. There are no instructions inside.4. My first assumption was that you put your tea leaves on top of the strainer and pour hot water into the jar. From reading another reviewer's comments, I learned that the water and tea go inside the jar, and the strainer keeps the tea leaves from getting into your mouth.Overall, the jar is an odd shape to drink from. It's too narrow, and the lip of the jar makes it hard to sip.
Answer: Screw off the top. Pull out the strainer. Put in one to two pinches of loose tea. Replace the strainer. Pour in boiling hit water. Steep for a few minutes with the cap back on. Then shake a but as the tea leaves tend to settle. Then sip careful as the tea can be quite hot. When finished with the tea, remove the strainer and spent tea leaves as leftover tea can stain.
