Which set is better for leak-proof lunches?

The Freshbox, on paper. Its lids are described as airtight and leak-proof, while PlanetGoods buyers complain the lids are hard to seal tightly. Neither is a dedicated lunch box, though.

Is the PlanetGoods 6-piece set really six pieces?

No. It is three glass containers plus three glass lids. Buyers on the product page call the six-piece label dishonest for that reason.

Both use durable glass, tempered for Freshbox and borosilicate for PlanetGoods, so the containers should hold up similarly. The lids are the weak point: PlanetGoods' glass lids draw sealing complaints, while Freshbox's plastic lids can wear or stain over time.

Can both go in the microwave and freezer?

Yes. Freshbox tempered glass is rated to -20°C and is microwave safe with the lid removed. PlanetGoods borosilicate glass goes from freezer to microwave to dishwasher.

Is the PlanetGoods set worth the extra?

It is the only one of the two with a stated price: $34.97 as of November 1, 2026. Whether it is worth more than Freshbox depends on the Freshbox price, which was not provided.

Which is better for large meal prep batches?

Freshbox lists capacities up to 3.1L, so it covers bigger batches. PlanetGoods does not state container sizes.
