Abstract: A handheld device for applying eyelash extensions is disclosed. The handheld device includes a device enclosure with an opening at a distal end of the device enclosure. The handheld device further includes tweezers at least partially disposed within the device enclosure. The tweezers are configured to grasp one or more lashes from a lash cartridge at least partially disposed within or coupled to the device enclosure. The tweezers are coupled to a tweezer actuator at least partially disposed within the device enclosure. The tweezer actuator is configured to selectively position the tweezers between a rest position and an extended position, wherein the tweezers are configured to extend the one or more lashes grasped by the tweezers through the opening at the distal end of the device enclosure when the tweezers are in the extended position.
