Where can I get drip tips for 306 Atomizer - 2.8-3.0 ohms and 306 Low Resistance Atomizer - 1.8-2.0 ohms that provape sells (both same in size)? I have 4 of them and cannot use them because drip tip that I have for 306 doesn't match them,yet it does match 306 that I bought from other vendor(cov). It seems like 306 from provape are "longer" and my drip tip is too short to properly fit them.
