These glass storage jars are made from borosilicate glass that is food-grade and BPA-free, providing a sturdy, nonreactive container for everyday use. They can be cleaned in a dishwasher or stored in the refrigerator, with the caution to remove the lid before dishwasher cycles and to wash the wooden lid by hand. The wide mouth design allows easy access for scooping and pouring, making it straightforward to handle ingredients like rice, flour, and sugar without spilling. The transparent, square shape lets you see contents clearly and monitor remaining stock at a glance, which helps you plan refills and avoid guessing when you are running low. A natural bamboo lid with a silicone seal creates an airtight environment that helps keep items fresh and protects against moisture. Although primarily aimed at pantry organization, these jars can also hold pet food, laundry beads, or bathroom cotton balls, depending on your storage needs. They are practical for storing a range of ingredients, snacks, and other items such as biscuits, tea, sweets, coffee beans, dried fruits, nuts, and spices. Each set includes 2-jars with labeling that resists oil and water, and the capacity and dimensions provide a useful sense of scale for home storage. Size: large.
