Materials: The jars are made from clear, fluted (ribbed) glass, often specified as durable and heat-resistant borosilicate glass. The lids and the multi-tiered stand are crafted from natural bamboo or wood.
Design Features: Each jar typically includes an airtight wooden lid, sometimes topped with a decorative crystal-style or gold-tone knob. The stand features a unique curved, "branch-like" design to hold the jars at different heights.
