Flat lashes boast a rhomboid-shaped base, enhancing their adherence to natural lashes for extended retention compared to traditional extensions. Primarily used to create Classic eyelash extension sets, they can also be used to excel in creating voluminous looks without weighing down the eyes. Their distinct weight distribution allows for the application of thicker lashes without compromising the natural lash integrity. Their rhomboid design also facilitates efficient tweezers handling, streamlining the application process.
