Built to be compatible with the Geek Vape G.Coil Boost Formula Series, these pods support both 0.4Ω and 0.6Ω coil options (sold separately), allowing you to switch between smooth flavor and dense vapor production. Thanks to the press-fit coil installation and snap-in pod connection, swapping coils and refilling is quick, mess-free, and hassle-free. https://www.vapeuniverse.co/products/aegis-boost-plus-pod-no-coil-5-5-ml?pr_prod_strat=pinned&pr_rec_id=43b52b1ed&pr_rec_pid=8277766045948&pr_ref_pid=7846687080700&pr_seq=uniform
