Each piece is 2cm wide! We often deliver them at 4cm, so please cut them to 2cm and apply. [52cm, Dark Brown C2] ※ Level Scale: 3 tones. Merit Hair: This is our original seal extension, a perfect blend of the highest quality Japanese-made artificial hair and the finest human hair. Although it's Merit Hair, it can be styled with curling irons and flat irons, and the quality is very close to human hair, so please rest assured. Over 90% of Remy hair on the market is hybrid. The quality of Remy and hybrid hair is exactly the same, making it impossible to distinguish even for professionals, but please be careful not to be deceived. Also, please note that the quality of Chinese-made artificial hair can be quite poor. We receive many opinions that the color is different from the photo, or that it is lighter or darker than the photo. Due to the nature of seal extensions, the appearance varies depending on the time of day, the way light hits it, and the lighting. There are also individual differences in quality, so please purchase at your own risk. Occasionally, buyers demand unreasonable returns, but we will not accommodate them. (Please be especially careful if you buy impulsively during the high season.) Especially, there are people who try to intimidate us by changing the number of extensions and claiming the color is different from what they expected, but please confirm that you are responsible for your purchase.
