Airtight Food Storage Container – Square Sandwich & Fruit Keeper with Silicone Seal
$12.99
Color: Gray
This airtight sandwich container is a slim square keeper with a silicone-sealed lid, measuring 8.07 x 8.07 x 1.30 inches. The shallow profile is the point: it slides flat into a laptop bag or tote instead of bulging, and it stacks level in a fridge without wasting shelf height. Suited to flat sandwiches, wraps, cut fruit, crackers and snacks; not to thick stacked deli sandwiches.
Slim enough for a bag that already has a laptop in it
Most sandwich containers are built tall so they can hold a stacked sandwich, then refuse to fit anywhere flat. At 1.30 inches deep, this one goes in alongside a laptop, a notebook or a tablet without forcing the bag open. If you carry lunch in the same bag you carry work in, that dimension matters more than volume does.
Silicone seal, not just a snap lid
The lid closes onto a soft silicone gasket rather than sealing plastic against plastic. That is what keeps cut apple from browning as fast and stops a container of berries from scenting everything else in the fridge.
Stacks flat in the fridge
A square footprint tiles against other square containers with no wasted gaps, and the low height means two or three stack inside the space one tall container occupies. Rounded corners make the inside easier to wipe out than a hard-cornered box.
Built as one piece
The body is moulded as a single unibody form with no glued seams or joints where food residue can lodge and bacteria can establish. Dishwasher safe and fridge safe. Available in Gray and Orange.
Pairs well with
Packing a full lunch: add the Stainless Steel Bento Box with Fork & Spoon for the main course, or the 4 Pack Snack Containers with Lids for Kids for smaller portions. For fridge organisation, see the Produce Storage Containers.
BPA & BPS-free with no toxins, or microplastics
Dishwasher safe and easy to clean
Unibody design doesn’t give bacteria anywhere to live
