The Planetbox Rover is a unibody system constructed from high-grade 304 (18/8) Stainless Steel. This choice of material offers exceptional durability and is intended for a lifespan of many years. The compartments are formed using a deep-draw pressing process, which creates a smooth interior without spot-welds or crevices where food particles could become trapped. This makes it an excellent choice for those prioritizing long-term hygiene and material purity, as there is zero plastic contact with the food.
Specifications indicate that the main stainless steel box is not intended for thin liquids; hydrostatic pressure can cause leaks at the lid margin. For liquid transport, the set includes "Big Dipper" containers with silicone lids that provide the necessary seal. The hinge is rated for over 10,000 cycles, and the entire unit is dishwasher safe, allowing for high-heat sterilization. Note that stainless steel is highly thermally conductive, so food will reach room temperature within about 60 minutes unless kept in the included insulated bag.
This kit also includes decorative magnets for the exterior, allowing children to personalize their lunch box. The latches are designed for durability, though they may require some initial practice for very young children. Key features include:
- High-grade 304 Stainless Steel for a plastic-free experience.
- Five-compartment layout for diverse snack packing.
- Dishwasher-safe construction for easy sanitation.
If the weight of stainless steel is a concern for a younger child, the Bentgo Fresh offers a much lighter polymer-based alternative with similar compartment flexibility.
