Colorful Wig Extensions Various colors and lengths. I received these as a gift, so I don't know the details. I was planning to make doll wigs and stored them unused. I believe there's a mix of heat-resistant and non-heat-resistant wefts. When applying heat, please test in an inconspicuous area, using a cooking sheet in between. - Color: Blue - Color: Pink - Color: Gray - Color: Green - Length: 100cm Thank you for viewing.
