Constructed from high-borosilicate glass, these 25 oz square jars offer high thermal stability and a non-reactive surface that won't absorb odors or leach into food. The square geometry is a practical choice for narrow shelves, as it utilizes approximately 22% more space than traditional round jars. This size is particularly well-suited for specialty items like loose-leaf tea, coffee beans, or colorful spices that benefit from a glass display.
The lids are made of bamboo and feature a silicone friction gasket to help keep contents dry. To keep the bamboo in good condition, it is helpful to dry it immediately after washing and occasionally apply a food-safe mineral oil. While the glass itself is sturdy and dishwasher safe, the bamboo lids are more sensitive to high humidity and temperature swings. These jars are a great fit for 1 lb bags of coffee, though they are too small for large bulk baking supplies.
For larger bulk storage needs, you might find the Oggi Jumbo 150 oz canister a useful addition to your kitchen.
