Kendo Vape Cotton
Kendo Vape Cotton is, among other things, a manufacturer of very high quality Japanese organic cotton. In its classic or Gold edition, this unbleached fibre presents properties much appreciated by vapers, because the atomizer wicks retain no smell if the e-liquid is changed. They sell packs that include their quality cotton and resistive wire to remake your e-cig coils.
Kendo Vape Cotton also manufactures flavour concentrates for e-cigarettes. You will be able to use them to make your own e-liquids. They are available as a 30mL format.
