Hello! I'm doing well, thank you. Regarding your search for a c-shaped isolating clamp for eyelash extensions, I highly recommend checking out Stacy Lash- lash extension tweezers. They have a product called lash extension tweezers, which are specifically designed for isolating lashes during extensions. These tweezers are polished by hand and would make a fantastic birthday gift for your mother, as they are both practical and loved by lash enthusiasts.
