If you’re looking for a classic smoking experience then we recommend either the Regular or Menthol flavor Refill cartridges. Njoy Refill cartridges are available in full, medium, light and nicotine free. Each refill pack comes with five cartridges and each cartridge is equal to approximately two packs of cigarettes. For a smoking experience most similar to traditional cigarettes, we recommend the “full” strength cartridges. •1 – Refill Cartridge Pack (five Cartridges) •Regular or Menthol Flavor (select at checkout)
