You can easily make delicious, authentic iced coffee. It's made of plastic, so it's lightweight and easy to use. It's a cold brew method. Instructions: Add 10g of coarsely ground coffee beans (fine grounds will pass through the filter) to 1 cup (120ml) of water and let it sit in the refrigerator overnight. Use the lid in photo ①. Change to the filter in photo ② and slowly lower it to extract the coffee. Delicious iced coffee is ready. Although not included with this item, I will also include a similar orange plastic coffee dripper. Thank you for looking.
