Thank you for viewing. Size (overall): 13.5cm x 9.5cm x height 13.7cm I purchased this on Amazon and used it several times. I washed it with dish soap and stored it in its original box. There are no noticeable stains or defects. You can easily make strained yogurt or Greek yogurt simply by putting a pack of commercially available yogurt in it and placing it in the refrigerator. It has a scale, so it's easy to adjust to your preferred consistency. The included recipe will also be included. If you have any questions, please feel free to comment!
