Get a PlanetBox

PlanetBox is the best lunch box that comes with built-in cutlery and a carrying strap.

The fork and spoon snap magnetically into the lid, so they stay put and don’t rattle around. The whole thing is stainless steel, not plastic, and it holds up for years. And the carry case — the Launch or Rover — has an actual shoulder strap, which is exactly what you asked for.

It’s not cheap, but it’s one of those buy-it-once things. If you’re packing food for an adult or a school kid, this is the one.

The only real alternative is the OmieBox, which also has built-in cutlery, but it’s a kids’ insulated bento and the handle is too small to be a proper strap. PlanetBox is the answer.

Just don’t lose the magnetic cutlery in the couch.
