The Izzy's Best Sellers Duo pairs the Zero Waste Mascara and Zero Waste Brow Gel in a bundle built for people who want high performance and a genuinely circular beauty routine. Both products arrive in medical-grade, American-made stainless steel tubes engineered to be sterilized and refilled up to 10,000 times, making single-use plastic packaging a non-issue from the start. Refillable stainless steel packaging designed for up to 10,000 use cycles, so the tube itself becomes a long-term tool rather than disposable waste. EWG Verified formulas free from parabens, silicones, and phthalates, with conditioning ingredients including olive oil unsaponifiables, tocopherol, and plant-derived waxes. Brow Gel available in four shades (CLR, BLND, MED BRN, BRN BLK) so the duo works across a range of brow tones and styling preferences. Vegan, cruelty-free, and gluten-free across both formulas, with ingredient transparency backed by EWG Verification. If you are ready to replace two everyday makeup staples with a refillable system that holds its performance standards, this duo is a practical starting point.
