STL CAPTAIN 3

Flexi-Lock — Captain 3

Gravity loses.
Curry stays put.

Turn it upside down. Shake it. Bury it under a laptop. We built the seal so you don't have to think about the seal.

A stainless steel tiffin system engineered around one uncompromising promise: what goes in, stays in — until you open it yourself. Mirror-polished interiors, a rust-free body, and a dual-tone carry pouch built for the vertical commute.

What's inside

Four things. Zero excuses.

01

Three 350ml containers

Sealed independently, not as a set — so the curry in tier one never finds out what's happening in tier three.

02

The pickle diplomat

A leak-resistant, food-grade pot that keeps salad, papad and pickle exactly where they belong — separate.

03

A pouch that stands up straight

Navy and sky blue, cut vertical on purpose — this bag was never meant to slouch in a backpack.

04

Steel that skips the rust

Mirror-polished inside, engineered to resist corrosion outside — the finish that ages the slowest in the bag.

Engineering notes

Ten reasons it never lets go.

10 / 10
No fine print
01

Sealed. Not just closed.

Airtight and leak-proof aren't the same claim — we make both. Tip it, drop it, forget it's in your bag. It holds the line.

02

Rust doesn't get an invite

Built from materials that simply refuse to corrode, so year five looks like day one — inside and out.

03

Stacks up, not out

Three meals, one column. The vertical build means your bag carries a tiffin, not a toolbox.

04

Lunch, untouched by transit

Flavour and heat arrive exactly as they left — sabzies, curries, rice, noodles, soups and stews, unbothered by the commute.

05

Steel that forgets its own weight

Mirror-polished inside, feather-light in hand — the paradox that makes daily carry effortless.

06

Made to outlast the habit

One tiffin, thousands of lunches. Durability here isn't a feature — it's the whole business model.

07

The pickle gets its own house

Food-grade virgin plastic, leak-resistant in its own right — because chutney has opinions about neighbours.

08

Nothing to Google, nothing to fear

BPA-free, full stop. One less ingredient list to worry about at lunchtime.

09

A pouch with a job to do

8mm heatlon lining wraps the whole stack in quiet insulation — warmth in, cold out, no exceptions.

10

Navy on the outside, intent on the inside

Sky blue accents on a navy body — a colourway that looks deliberate because it was.

What it's for

Say the dish. It already fits.
