HARIO Immersion Switch 200ml SSD-200-B Kalita Coffee Dripper Wave Series for 1-2 people, Glass Dripper, Heat-resistant Glass, Black WDG-155 This is a combined sale of the above two items. Both were only used twice, but I am selling them because they didn't suit me. I think only a few Wave filters were used, but I haven't counted them, so I'll include them as a bonus. Both items have no major scratches, but there are minor scuffs and scratches. There are also parts that do not appear in the photos, so please understand this before purchasing.
