These were likely purchased from SHEIN. They are a set of three: two gray-ash extensions (approx. 55cm) and one gold-toned white extension (approx. 49cm). They are the clip-in type. Only the gray ones have been used once. There are no noticeable stains, and they have been disinfected with alcohol, but please purchase only if you understand that they are used items. Immediate purchase is welcome.
