• Estrid’s refillable antiperspirant redefines sustainable rollerball deodorant by separating reusable parts from disposable ones
• The design uses a durable polycarbonate roller ball and a recyclable twist-in refill cartridge.
• Designed by Sample Studio, the project spans full industrial design execution, from early concept and functional 3D-printed prototypes to high-fidelity 3D renders created for product marketing.

This refillable rollerball deodorant system feels like such a smart, satisfying leap forward. It’s sleek, minimal, and genuinely beautiful without trying too hard. The brand is called Estrid, and Sample Studio is the design agency behind the packaging.
