metal lunch box 3d model

A high-quality 3D render of an open modern insulated lunchbox showing a fully detailed interior. The inside features a double-wall stainless-steel inner chamber with a visible polished metal finish. The inner walls have smooth filleted corners (rounded edges) for easy cleaning. Show the insulation structure clearly: a thin gap between the inner stainless-steel bowl and the outer shell, suggesting thermal insulation. Add a soft gray silicone gasket running continuously around the rim of the lid and the base for leak-proof sealing. Inside the lid, show embedded circular neodymium magnets positioned in small recessed pockets. Include a smooth 180-degree hinge connected to the back. Add an optional removable inner tray with subtle grooves for organizing food. The outer shell should be natural wheat-fiber polymer with a matte beige finish. Lighting should highlight the metal surfaces and gasket details. Ultra-realistic product render style.”
