I have this french press type travel tea mug as well. Although it is not leak proof (i can't throw it in my purse like my other one), it keeps all the tea leaves at the bottom. Also from David's Tea.
Pink Flamingo- David's Tea sweet, citrusy cocktail of oranges, tangerines and lemongrass. It’s got hibiscus and beetroot to turn it a natural shade of hot pink, plus blackberry leaves for a sunny burst of Vitamin C, apple and carrot for extra sweetness, and eucalyptus leaves for kick.
