No. This brand of tea will say if "individually wrapped" if it was. These are just the tea bags.

What material is cristal sachet made of?

Sadly I must report plastic. As I do you can simply release tea leaves into a ball for steeping. Hope this helps.

Does this tea come out pink? What color is it after it has been infused?

Hello, thank you for your inquiry. The tea does not brew pink. It is a flavored black tea. For a brew that's pink, that would be Nuit d’ete which is an herbal infustion with a base of hibiscus.

Does this tea contain natural flavors?

This is what it says on the box: Ingredients: black tea, strawberry bits and redcurrant flavors (redcurrant, raspberry, strawberry, cherry) I love it!
