Warning: this is not for your ears, but for your Kiwi pod, version 1 or 2. This pack of five clean sticks from Kiwi Vapor provides a thorough cleaning of the drip tip and the space in which you insert the cartridges to get rid of all dirt and e-liquid residue. To keep your e-cigarette healthy and hygienic, we recommend a little cleaning every time you replace the cartridge.
