Trio Stainless Container

Plastic-free

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

Plastic-free 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 - genuinely plastic-free, not just "BPA-free plastic." It won't leak dry or semi-dry foods; for soups and wet foods LunchBots offers a leak-proof version with a silicone-sealed lid (silicone-only rather than fully plastic-free).

Pros

  • Fully plastic-free (classic lid) - steel body and steel lid
  • 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
