These are clip-in hair extensions I recently purchased overseas. They are a set of two colors, pink and red. The red ones are unopened, but the pink ones were opened once for inspection. I am selling them because I no longer have plans to use them. The length is approximately 60 cm. I am unsure about heat resistance, but it was labeled as high-temperature fiber, so I believe they are heat-resistant. No price reductions No individual sales Immediate purchase OK Thank you for looking.
