... As of Nutzen.Ich befülle this "egg" with 3 teaspoons Kräutertee.Dieser may then with me in a high glass carafe little longer drag (30 min.). After 15 minutes, then is the "egg" on the decline since the bubble in the lid does not carry the weight of tea after swelling as buoyancy ausreicht.Leider it's all (for me) not more benefits than other tea eggs for 3 Euro looks for but prettier (yes also what).
