Say hello to a deliciously unique pre-filled disposable device from HEYLO. The HEYLO is portable, compact, and consists of up to 800 puffs. Heylo uses an alternative to nicotine with 10% guarana extract, a Brazilian plant native to the Amazon basin. All HEYLO require no maintenance, charging, or refilling. After your HEYLO runs out of juice and/or battery, simply buy a replacement.
