Question: Can you use a tea bag as well or only loose leaves?
Document: I've bought one for myself, mom, and mother in law. Easy to wash. Perfect for loose leaf tea, I use the strainer for other cups as well. These cups hold the heat in for your hot beverage. Very happy with the product.
Got this for my wife who is definitely a tea enthusiast (snob). She uses it at work where she complained that even with loose leaf tea, she could never get the taste right. None of her other infusers that she was comfortable taking to work had much room for the leaves to bloom. The basket/infuser in this brewing system has more than ample room for the leaves to do their thing and give the tea as much flavor as possible.
This is such a gorgeous tea glass. After reading reviews I am very careful with it. It does appear that it could break or chip if not handled properly. I hand wash it so it won't get damaged in a dishwasher. Colors are true to the picture, goes with my oriental white and red office. I love the taste of loose tea leaves...better flavor than packaged tea bags. It did take a while getting delivered, about two and a half weeks so don't expect it quickly.
It's a very cute cup. It makes brewing loose leaf tea very convenient. The fact that it didn't have a handle didn't bother me, as it actually made it look cooler. The only complaint is that the lid doesn't stay on too well, but that's not much of a necessity anyway.
Then again, if I was in that much of a rush, I'd probably use some bagged tea, too.The mug is a porcelain or porcelain-type material- beautiful, strong, and good quality, and the top and strainer both fit well, and are very functional and easy to clean.
The cherry blossom design is beautiful and the steeper works well. Some loose leaf makes it through but overall not bad. I gave the 3 star for the lack of handle or heat sleeve. When the tea is hot the mug gets hot and is hard to hold without a handle or rubber heat sleeve.
I had one of these tea glasses and I loved it. It is so easy to put loose leaf tea (or a bag) in the strainer. Then, add hot water to the glass and it makes the perfect cup of tea! The strainer is so easy to clean and I haven't had any bits of loose tea escape into my drink.The lovely cherry blossom pattern of this tea glass makes it even more special. Another bonus?
upon recieving this item i noted the sturdy packaging it came in, the cup itself is thick and well made, has a solid feel to it and does not heat up to the point of discomfort when full of freshly heated water. the infuser and lid fit as they should. overall i am very pleased with this purchase, its simple to use and produces a nice cup of tea anytime with little effort.
ordered this for work to conveniently brew loose tea  & it works great, I liked it so much I ordered a 2nd one for myself & another for a friend!keeps tea hot & is easy to use.
I love this item!! I ordered loose mulberry tea to drink with this cup and have really enjoyed the ease of use. Cup is warm with hot water, but no so that I can't pick it up to drink. Use it everyday and also easy to clean! Thanks! !
Answer: Yes both work, but you are buying a product more made for loose tea since it comes with a loose tea infuser. Save your money and use a regular mug if you want to use a tea bag.
