Sistema Tritan Ultra Square Container – 450 mL Airtight

Sistema Tritan Ultra square container — 450 mL, airtight clips for fresh, on-show storage

In simple terms: this is a small, ultra-clear storage box that keeps food fresher for longer. The Tritan™ body looks like glass but won’t shatter; the gasketed lid and signature Sistema clips push air out as you lock them down. Use it for snacks, spices, leftovers or craft bits—you can see exactly what’s inside, and it stacks neatly with others.

At 450 mL (1.9 cups), this compact square (10.2 × 10.2 × 6.1 cm) is tuned for everyday portions without wasting shelf space. The airtight seal protects flavour and crunch, while the impact-ready Tritan walls stay crystal-clear through daily use—dishwasher, freezer and microwave safe. Designed and made in New Zealand for dependable performance.
