Each piece is 2cm wide! We often deliver them at 4cm, so please cut them in half 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, so please be careful not to be deceived. Also, please note that the quality of artificial hair can be significantly lower if it's made in China. We receive many opinions that the color is different from the photos, or that it's brighter or darker than the photos. Due to the nature of seal extensions, the appearance varies depending on the time of day, the lighting, and the individual's perception. Please purchase at your own risk. Occasionally, buyers demand unreasonable returns, but we will not accommodate them. (Please be especially careful if you are buying impulsively during peak season.) There are some 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 purchasing at your own risk.
