The ice pack that fits the box, not the cooler.
Most “slim” packs are still too wide for a kids bento. ChillSlab is a thin slab cut to the well beside yogurt — so the sandwich stays cold and the lid still closes.

4-pack freeze two, pack two
From $11 at launch
Yogurt should not be warm by recess.
01
Thin enough to nest
About half an inch thick. Slides beside a tray or a food jar instead of sitting on top of the sandwich.
02
Cold through lunch
The gel is mixed to stay cold for hours in an insulated tote — not just the ride to school.
03
No puddle in the bag
Seams are leak-welded. The shell is food-safe. Rinse it. Freeze it. Pack it again tomorrow.
About 6.5 × 4.25 × 0.4 in
Sized for a kids lunch box, not a beach cooler. Two in the freezer. Two in the bag. Soft sage and cream so they don’t look like camping gear.
