These reusable tea bags are made from GOTS certified organic cotton muslin, as well as an organic cotton cording. They are approximately 2.5" x 2.25", but due to the handmade nature of this item, they will vary in size slightly. 
Washing instructions:
- Hand wash before use
- Once tea leaves have dried, they should dump out easily.
- Rinse out with hot water after every use to remove any remaining bits of tea and hang dry.
