There's a specific moment every parent of a tween or teen hits: the lunch box that worked fine last year suddenly gets rejected on sight for looking too "kid." The Core stainless steel bento was built for exactly that moment.
A stainless steel base with a clear plastic lid and a 4 clip closure, the Core trades bright cartoon styling for something that looks more like gear an adult would actually use, because that's precisely what a lot of older kids are after.
What Makes the Core Different From the Rest of the Range
- Material: A stainless steel base instead of plastic, more durable and a more grown-up feel in the hand.
- Removable divider: A T-shaped plastic insert splits it into 3 compartments, or lifts out entirely for one big single-compartment box when a bigger appetite calls for it.
- Styling: Solid colourways rather than character prints, which tends to matter a lot more once kids hit the tween and teen years.
Why the Removable Divider Matters
Appetites at this age swing more than people expect, some days it's a proper three-part meal, other days it's one big serve of pasta or fried rice. Being able to pull the divider out entirely rather than being stuck with fixed sections means the Core keeps up with both.
Who the Core Suits Best
- Tweens and teens who've rejected "kid" lunch boxes
- Bigger appetites that need real capacity, not just compartments
