Throw those old-fashioned tea balls away! These convenient one-use bags allow your tea to expand when the leaves rehydrate. This allows better water circulation and the full flavor of the tea is released into the liquor. Size #3 fits 4-6 cup (medium to large) teapots. Box of 100. Perfect for our Blueberry or Strawberry Fruit Infusions that expand to triple their size when steeped.
