Overview
Tanjiae's 4-pack of 8oz stainless steel snack containers pairs 18/8 steel bodies with silicone lids, sized for kids' portions and built to stack inside each other for storage.
The stainless steel body is the main selling point over plastic snack containers: reviewers specifically call out that dropping one does not risk cracking it the way a plastic container would. At 8oz each, the size is aimed squarely at younger kids' portions rather than adult meal prep, and the lids come off to let the containers nest inside each other rather than the sealed units stacking.
- 4-pack of 8oz (1 cup) containers, about 3.8 x 2.9 x 1.9 inches each
- 18/8 stainless steel bodies with silicone lids
- CPSC, CPSIA, and LFGB tested for no BPA, lead, or phthalates
- Dishwasher, freezer, and oven safe
Who it's for
Good for packing snacks or small portions for kids roughly 1 to 3 years old, or for adults doing strict portion control. Not sized for a full meal or larger snacks, since each container only holds one cup.
What buyers say
From Amazon customer reviews.
Reviewers like these for travel, school lunches, and portion control, calling out that the stainless steel body will not crack the way plastic does if dropped, and that the silicone lids seal well enough for snacks like grapes, crackers, or trail mix through the dishwasher. One reviewer was less confident the lids would hold up with liquid contents. A separate review flagged a quality issue: the containers they received had a rim lip that was not folded over enough, leaving a sharp edge on the metal that they considered unsafe.
Strengths and trade-offs
Drawn from this product's published specifications.
- Stainless steel resists cracking if dropped
- Silicone lids reviewers describe as leakproof for snacks
- Stacks inside itself with lids off to save space
- Dishwasher, freezer, and oven safe
- One batch had an unfolded, sharp rim edge
- Lids may not fully hold liquid per one reviewer
- 8oz size suits small portions, ages 1 to 3
Performance notes
18/8 stainless steel bodies with silicone lids are what make these dishwasher, freezer, and oven safe, and the lids seal fully only when pressed down around the entire edge, which is worth checking each time to avoid leaks. The containers nest inside each other once the lids are off, which is how they save space in a fridge or cabinet rather than the sealed units themselves stacking.
