These extensions were applied at a salon for about 25,000 yen. I counted roughly, and I confirmed 63 pieces. I have 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 is a self-assessment, 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 your purchase.
