Guava - Guava is just as pure as authentic guava can taste. Rich and cancerous smell and taste that quench this truly exotic and refreshing feeling. Love guava all over again and enjoy a tropical break in the sun, worry free and really enjoy the wonders of life. NKTR Guava is made with TFN ® Nicotine is the only genuine nicotine brand that is not derived from the leaf, stem or waste dust of tobacco. TFN ® Nicotine is odorless and tasteless while providing a purer and refined flavor profile.
