Lash Separation: Used by the technician to comb and separate extended lashes during and after the procedure to ensure there are no clumps (or "stickies"). Styling: Applied to give eyelashes and eyebrows the desired shape, styling them before applying primer or after the glue has set. Application: Can be used for the even distribution of mascara, brow gel, or specialized care serums. Hygiene and Aftercare: These wands are a disposable item, which ensures a high level of hygiene. Technicians often give them to clients for daily at-home care of their eyelash extensions.
