Your eternally loyal companion for your makeup bag is here! This refillable mascara tube is perfectly suited for your Green Couture Endless Lashes Refill Mascara. The high-quality refillable mascara unit is made of 50% recycled plastic and is ideal for filling with the refill. The used inner bottle is very easy to replace. The outer bottle and cap can be reused indefinitely 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 bears 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.
