These are currently popular slim tack extensions. There are 18 blonde and 35 brown extensions, for a total of 53. I've used them for about two and a half months, but the hair quality is still beautiful. These are genuine extensions from a famous salon specializing in slim tack and feather extensions, so the hair quality is guaranteed. New extensions at the salon cost about 800 yen per piece, so these are recommended for those who want to add more extensions or don't plan to wear them for more than six months. I will send them to you straightened and silky smooth with a Hair Beauron iron.
