Replacement brush heads specifically for Panasonic Doltz electric toothbrushes. I received a large quantity as samples, so I am selling them. Of course, they are new, unused, and unopened. As shown in photos 2 and 3, they are individually packaged. Please note that the brush colors may be a mix of white and black. The product number is likely EW-0914. (Although I received them as samples, so I'm not certain, they appear to be compatible with Panasonic Doltz electric toothbrushes.) I am selling a set of 30 at a low price, so please refrain from price negotiations. Feel free to ask any questions you may have.
