Your eternally loyal companion for your makeup bag is here! This refillable mascara tube is perfectly suited for your Green Couture Multi Lash Volume Refill Mascara. The high-quality refillable mascara unit is made of 50% recycled plastic and can be easily filled with the refill. The used inner bottle is very simple to replace. The outer bottle and cap are reusable as many times as needed and can always be refilled with the corresponding refill. ARTDECO has consciously chosen FSC Mix cardboard, sourced from responsibly managed forests and plantations. Therefore, the folding box is marked with the FSC Mix symbol. To refill, follow these steps: Step 1: Pull the empty refill out of the outer bottle. Step 2: Remove the outer cap. Step 3: Click the new refill into the bottle. Step 4: Put the outer cap back on, and you're done.
