Step 1: Put loose leaf tea in a mug
Step 2: Fill mug with hot water
Step 3: Dip your tea straw in, give it a swirl and sip!
The base acts as a filter and will prevent you from sucking up tea leaves!
You can detach the base filter to wash your straw.
Will you burn your lips? Nope, you won't. But of course we assume you are sensible and don't slurrrp up piping hot water fresh off the boil!
