LunchBots Trio Stainless Container

Recommended

All 18/8 stainless container with a stainless lid - no plastic lining, no coating, and no plastic or silicone in the food path.

The verdict: Plastic-free

Body and lid are both 18/8 food-grade stainless steel with no plastic lining, coating, or gasket on the standard (non-leakproof) models. Nothing but steel touches food. Note that LunchBots' leak-proof lids add a silicone seal (those are silicone-only).

A simple, durable stainless steel bento-style container. The classic Trio has three fixed compartments and a snug stainless lid. It holds dry and semi-dry foods but won't seal soups or wet foods; for those LunchBots offers a separate leak-proof version with a silicone-sealed lid. Dishwasher safe.

Pros

  • Indestructible; no staining or odor retention
  • Dishwasher safe

Cons

  • Not leak-proof unless you buy the silicone-sealed version
  • Cannot go in the microwave
  • Fixed compartments limit flexibility
