The Innokin Ucan is the first and by far the best stainless steel eliquid bottle ever made. This sturdy 10ml dispenser is beautifully crafted from solid 304 stainless steel and exudes quality. The Ucan is constructed to faithfully maintain the pure taste of your eliquids. The metal tip retracts against a plastic insert in the twist-off cap to prevent leakage and insure that you will never be surprised by a sticky mess in your pocket or purse. Eliquid is dispensed in individual drops or continuous flow by pressing the bottom pump-action button.
