Smok Acro replacement pods [ SOLD AS PACK OF 3 ] can store up to 2ml of e-liquid and may be refilled several times. They also include a built-in coil for added ease; instead of fiddling with messy coil swaps, you can just replace the entire pod when the coil’s life runs out. Remove the pod from the device, open the silicone stopper, and fill with your preferred e-liquid.
