LP Series stands for “leak-proof”. All of these cartridges work well with thin oils but only two work well with thick oils. If you have a thicker oil solution, it is best to stay away from the silver leak proof style vape cartridges as they work best with thinner oils.
If time is money, and your oil is precious to you... Then we 100% recommend our Leak Proof Series. You won't have to worry about losing oil due to leaky cartridges or wasting your time filling cartridges that are just going to leak on you anyways.
The Leak Proof series is pinnacle of vape cartridges. We have sold millions of high quality vape cartridges to satisfied clients. However, be careful for other clone vape cartridges. They may look similar to the original supplier but they are made with inferior materials and put together with low quality control.
