To use these 5D mink false eyelashes, first apply a thin layer of eyelash glue along the lash band. Wait a few seconds until the glue becomes tacky. Then, carefully place the lashes as close to your natural lash line as possible. Press gently to ensure they stick well. When removing, use an oil - based makeup remover to dissolve the glue and gently peel them off. For maintenance, store the lashes in their original case after each use. Avoid getting them wet as this may damage the mink hair. With proper care, these lashes can be reused multiple times.
