The evolution of the Prism tank continues! The Innokin Prism T20-S is purpose-built for vapers looking for a mouth to lung (MTL) vaping experience with exceptional flavor. Innokin has finally given Aspire some serious competition in the mouth-to-lung (MTL) market. The Prism T20-S features a 2.0ml juice capacity and an easy to use top fill design with a twist off cap. The Endura Prism S coils are provide an ideal draw and airflow resulting in the ultimate MTL flavor experience. The kit comes with two atomizer heads, 0.8 Ohm and 1.5 Ohm. The 0.8 Ohm coil provides amazing flavor and a looser draw while the 1.5 tightens up the draw for vapers who prefer that though it does reduce the flavor a bit.
