These extensions were applied at a salon for about 25,000 yen. I counted roughly, and I confirmed 63 pieces. I only used them for one day. As you can see in the pictures, they are still shiny. The longest hair is about 46cm long. I had the extensions, which were originally chest-length, cut to a length that suited me. Therefore, the lengths appear to vary, but they were perfectly usable. The adhesive parts were removed directly from my hair. I removed as much hair as possible, but please be aware that this was done by an amateur, so those who are concerned should take caution. The adhesive parts have not been processed. After removal, they have been cleaned and straightened with a hair iron to remove any kinks. This product is non-returnable. Please check the product condition in the photos and comments before purchasing, and make sure you are satisfied before making a purchase.
