●Remove the cartridge cap by turning it in the direction of the arrow (OPEN mark). ●After that, turn the holder to the right and pull out the core by 1-2mm before using. Because the core is soft, please be careful not to put out too much. ●After use, replace the wick and turn the cap to close tightly. (If you leave it unclosed, the core will break or become hard and difficult to draw.) ●It is recommended to use an oil-based eye makeup remover to remove the eyebrows as they are difficult to remove. ●When replacing the core, pull out the cartridge (this product) from the holder and insert a new product. <How to set to the holder> ●Use it by setting it in the separately sold “MAQuillAGE eyebrow holder”. ●Insert the cartridge (this product) into the hole in the above holder until it clicks. ●Tools can be set by removing the attached cap.
