The tea diffuses very nicely and can be multiple times, 3 times is recommended.
The tea bag itself is just too biodegradable, so unfortunately the contents will spill out into the water if you're too rough, and you'll then have to sieve it out.
Other than that, they come individually packaged so is great to taking out and using later, and above all, they really work!
Just don't take it at night, it will keep you up! No literally, the black tea has fairly strong caffeine content, which I am very pleased with myself.
Thank you Nutra Tea!
