This is a Sharer Dowa dust collector. I purchased it about two years ago and used it in my home nail salon for about six months. After that, I bought a new one and have been storing this one at home. The filter is washable, and I have washed it several times. However, there is some pink discoloration, but I think it can still be used. In the 4th and 5th photos, there are some acetone stains and minor scratches. The adapter was wrapped in plastic wrap when used, so it is almost free of stains. Color: White系 (White-based)
