Available Options
Same matrix.
Bigger
appetite.
The same clip-locked steel box, scaled up for the lunch that doesn't fit in one polite portion. More room inside, same seal on all four corners, same three colourways to choose from.
Same proof. Bigger numbers.
Eight reasons the clip never quits, at any size.
Large edition
Four corners, four clips
Locked at every corner instead of one central latch, so pressure is distributed — not just held on one hinge.
Rust doesn't get a vote
A rust-free steel body that keeps its mirror finish through years of dishwashing and daily transit.
Bigger footprint, same footprint discipline
Scaled up in depth and width, not just marketing copy — still flat enough to slide into a bag pocket sideways.
One box, a full meal
Room for rotis, rice, and a side without anything touching lids or getting left at home for lack of space.
Mirror finish, minimal effort
The polished interior wipes clean in seconds — no ridges for last night's gravy to hide in.
Colour is cosmetic, not structural
Pistachio, pink, or sky blue changes the lid tone only — the seal and the steel stay identical underneath.
BPA-free lid, every colourway
The tinted lid is BPA-free across all three variants — the palette changed, the safety standard didn't.
Light enough to forget it's steel
Full stainless construction that still feels light in a bag — durability without the weight tax.
One compartment, sized for a full plate.
One datasheet, one size up.
Everything that made the original work, carried over — just built into a body with more room to actually pack a meal.
