Since it's often delivered in lengths of meters, please cut it into 2cm pieces and apply. [52cm, Original Color Silver Ash] Merit Hair: This is our original seal extension, a perfect blend of the highest quality Japanese-made artificial hair and the finest human hair. Regarding 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 even for professionals to tell the difference, so please be careful not to be deceived. Please also note that the quality of artificial hair can vary greatly, especially with Chinese-made artificial hair. We receive many complaints that the color is different from the photos, or that it appears lighter or darker. Due to the nature of seal extensions, the appearance varies depending on the time of day, the lighting, and the individual. Please purchase at your own risk, as there are individual differences in quality. Occasionally, buyers demand unreasonable returns, but we will not accommodate them. (Please be especially careful if you are buying during peak season.) In particular, some people try to intimidate us by claiming the color is different from what they expected after changing the number of extensions. Please confirm that you are taking responsibility for your purchase before buying.
