I took these camping this weekend (with some other teas, but forgot the tea bags/strainer), and OMG. SO GOOD.
I could let them steep for ages, and in a 12 oz cup 2 of them gave me 3 good cups of tea. Plus, it was really fun pulling them out of my ceramic mug and holding them up (like kraken! or sea urchins!) when people asked me what I was drinking. :D
