The Cleito Tank by Aspire is more than meets the eye! The Cleito is a top-fill tank that works with new pre-built heads in the shape of cartomizers and each coil head has a chimney attached to it. The tank uses a revolutionary new coil design (clapton style Kanthal coils) that free up even more restriction in the airflow by eliminating the need for a static chimney within the tank itself which results in an expanded flavor profile and increased vapor production. This tank is truly a refined product from Aspire. It has a clean, minimal look that belies its complexity. The gold-plated 510 pin is non-adjustable and has great conductivity. The Aspire Cleito cuffs come in four different colors to help dissipate heat and allow color coordination with for personal preference or to use them as a visual cue for identifying e-liquid. The Aspire Cleito tank is made of a Stainless Steel (304) construction with a glass tube and a wide bore Delrin drip tip. You may also use your own standard 510 replacement drip tips as well like Still Chucks 'Cleito Curve' drip tip!
