I purchased this on Mercari previously. After comparing it with a paper dripper, I personally preferred the paper dripper, so I will be selling this as I will not be using it in the future. I have only used it once myself. I don't think there are any noticeable stains, but there may be some minor dirt as it has been used. Please refrain from purchasing if you are looking for perfection, as this is based on a casual inspection.
