Sistema Brilliance

New Zealand-made Tritan plastic containers with a unique clip-lock system and integrated silicone seal. They're genuinely leak-proof — the kind where you can shake them upside down over your laptop and nothing happens (we tested). A 3-pack of medium containers costs about $15. The Tritan plastic is BPA-free, stain-resistant, and survives thousands of dishwasher cycles without clouding. The modular sizes stack and nest logically. Sistema solved the leak problem that plagues 90% of plastic containers, and they did it for $5 per unit.
