NBN Stainless Steel Tea/Coffee Diffuser. These are excellent for loose leaf tea or I use it for fresh ground coffee beans using plunger size, excellent for travelling with or using at home.
Simply place tea or coffee into the strainer pour over hot water and place the lid on to capture the flavours. Let sit for a period of time required then take off the lid flip it over and place tea diffuser into the lid. Drink your tea or coffee.
I have had mine for years and use it daily. Great gift too with a bag of coffee or tea.
