HongXing UV 3-Compartment Steel Lunch Box 750ml 304# | Factory Direct

The three-compartment version of the UV ins-style series adds the portion-balance architecture to the same high-gloss proposition. Three sections at 750ml total deliver the classic balanced-lunch layout: starch, protein, and vegetable — each compartment sized for a standard portion, with full-height steel walls keeping the three components separated from packing to eating.

The 304# stainless steel tray is the structural and hygiene core. The food-contact surface resists odour accumulation and staining from tomato and turmeric across repeated use — the steel advantage that plastic compartments cannot replicate. The tray's section dividers are part of the moulding — no separate inserts to lose, no divider misalignment during assembly or washing.

The UV-gloss exterior — Pink, Blue, or Purple — is the visual proposition: a high-shine, ins-style finish that photographs well and sits well on a desk. The PP lid closes over a full-perimeter silicone gasket with snap-lock closure. The PP fork-and-spoon set stores in the lid channel.

At 750ml, the three-grid format is slightly smaller than the two-grid 800ml but delivers more section granularity — the trade-off that suits the portion-structured eater who prefers three balanced components over two larger sections.

For wholesale buyers, the two-grid and three-grid UV boxes display side by side as a section-count choice within one design family: two-grid (800ml, rice + combined sides) and three-grid (750ml, rice + protein + vegetable). One supplier, one material story, two portion architectures.
