The Sinnsally Bento Box is designed as a mid-tier lunch solution for both adults and older students. It features a 2.2mm thick Polypropylene chassis, which provides enough rigidity to withstand drops from about one meter. The four-latch locking system is paired with a silicone-injected gasket that helps isolate compartments, preventing flavors from migrating between sections. This design is optimized for viscous liquids like yogurt or thick sauces.
Specifications indicate that the Polypropylene base can handle temperatures up to 120°C, making it safe for standard microwave reheating. To maintain the seal's effectiveness, it is best to hand-wash the lid, as the high heat of industrial dishwashers can cause the silicone to warp over time. Additionally, allowing hot food to vent steam for 30 seconds before locking the lid helps prevent a vacuum effect that can make the container difficult to open later.
This bento box includes an integrated utensil set, which helps keep all lunch components in one place. The material is BPA-free but may retain colors from tomato-based sauces due to the natural porosity of the plastic. Useful feature highlights include:
- True compartment isolation for organized meals.
- High thermal stability for microwave use.
- Integrated storage for included utensils.
For a version with even higher heat resistance and zero stain retention, the Bentgo Glass Lunch Box is an excellent alternative for office environments.
