Loose-leaf tea and Matcha blends in test tube - filled with our most popular blends. Our test tube containers are approximately 6", topped with a cork and shrink band sealed. Ingredients and expiration date are clearly printed on the label applied to the tube. Each test tube yields approximately 4 cups of brewed tea. All our teas are non-gmo, fair trade compliant, sustainably sourced, gluten-free, lactose-free and calorie-free. The acrylic display rack is now available here. We've been producing these for some years now and have had a preference for glass test tubes but we have had trouble with our supply since the pandemic. We now use either glass or plastic depending on what we have available. The difference is discernible primarily by the weight with the glass being heavier and of course more susceptible to breakage.
