These items are junk. They have been stored for a long time. Some are missing caps. Used items are in their current state, with bristles that are loose and clumped together. The condition is poor. New items also show signs of aging due to long-term storage. I don't know much about them, and the material of the bristles is unknown. I will consider them as junk items. Please refrain from purchasing if you are sensitive to this. Please refrain from purchasing if you are looking for perfection. The boxes are dirty. The loose brushes will be bundled compactly. I hope that those who understand that these are junk items will consider purchasing. No individual sales.
