This box is perfect in many ways, but it is not an airtight container. This means that humidity, air, and smells can go into the box even though the lid. You could put your herbs in this box, no one is going to prevent you from it but you are at risk that your tea comes with a different taste or not as strong as you intended. For unwrapped tea bags or leaves it is better if you save them in a tin so they are fresher, and for your tea bags, this box is the perfect deal. Hope this helps!
