All buttons have been washed, but still have a slight vinegar smell to them as they have been sitting in jars for quite some time. The smell is due to the celluloid breaking down since they are vintage. You may want to wash them again when you receive them. The buttons vary in size, color, and type. There are 2-hole, 4-hole, and toggle-type buttons in every pound. Some buttons have defects, so I am selling them with the disclosure that some may be flawed in some way. Flaws may include: discoloration, rust/oxidation/tarnishing on metallic parts, and smell of vinegar. Please ask questions if you need to!
