The Shine/Ace pods allow users to see how much e-liquid is left with a transparent window. To refill, unplug the side silicone stopper and fill with an e-liquid of your choice before securing back in. The use of organic cotton wick offers consistently clear flavour. Due to the 1.0 Ohm coil resistance, these pods are most suited to high PG e-liquids of 50% and above, as well as salt nicotine e-liquids for a smooth throat hit.
