It is not a drip tip.
It is designed to prevent your e-liquid from leaking through the atomizer, thus eliminating the mess and and preventing damage to your e-cig "internals" that is caused by leakage.
They contain two O-rings and two air holes that can easily be widened for more airflow.
Originally for 901 atomizers, but they work perfectly with 510 atomizers on an eGo battery or on any mod via a 510-510 adapter.
