Abstract
Enhanced structures, devices, and techniques allow fluids and liquid products, such as cosmetics, to be applied in a cleaner and more effective manner. Various embodiments of fluid dispensing apparatuses are provided which employ fluid communication materials for promoting effective and repeatable fluid dispensing during use and resisting unwanted migration of fluids during non-use.
