This is a Hario Immersion Dripper, model SSD-200. It includes coffee grounds, and with water filled to the brim, it holds about 220-240g, which should be enough for one person. I wanted to brew two servings in a mug, so the capacity wasn't enough, and I'm going back to my previous method. This is a used item, so please refrain from purchasing if you are overly concerned about condition. Thank you for looking.
