Our take on the PlanetBox Square Glass Food Storage Container

The PlanetBox Square is a 20 oz clear glass food storage container built for meal prep. It is dishwasher safe and freezer safe, so it moves from prep day to the freezer to the dishwasher without special handling. Glass means no staining or lingering smells from sauces and curries, which is the main reason people pick it over plastic. Its only recorded price is $11.16 as of November 1, 2026, so there is no lower recent price to wait for.

Questions and answers

Is $11.16 a good price for this container?
It is the only price recorded for this container, dated November 1, 2026, so there is no lower recent price to compare against. At that price a single 20 oz glass container is in line with typical glass meal-prep containers.
Can it go in the freezer and dishwasher?
Yes. PlanetBox lists it as both dishwasher safe and freezer safe, so it can go from freezer to thawing without hand washing.
Is 20 oz big enough for a meal?
20 oz holds a single lunch portion or a side dish for two. It is small for full family meals or large batches of soup.
Does it leak in a bag?
The listing does not state the lid material or a leakproof claim. Treat it as fine for upright transport and check the lid seal before packing it sideways.
Can I microwave it?
It is glass, which is generally microwave safe, but the listing does not give a microwave rating. Reheat without the lid unless the lid is marked microwave safe.
What comes in the box?
The listing describes one clear 20 oz square glass container. It does not specify whether a lid is included, so confirm that before ordering.
What do buyers say about the PlanetBox Square Glass Food Storage Container?
Rated 4.3 out of 5 from 6 ratings.
