i received three canisters to review (photos attached are of the smaller two sizes; the smallest is holding garlic). the glass doesn't feel burdensome even at the largest size, though i don't want to test chip or shatter durability. the tops feel a bit flimsy and are easily dented, but i appreciate the handle grooves for the ease of opening with one hand (vs needing to have a wide open palm to pull it off). i won't be storing anything that i prefer to be more airtight in the future, but they're great for dog treats and storing H*nest K*tchen (something we use twice a day, daily).
