Frequently Asked Questions

ExpandaLid® comes as a complete set, with a glass container perfectly paired to each lid size. Each set includes 3 lids and 3 matching high‑borosilicate glass containers.

ExpandaLid® lids are uniquely engineered to pair with our containers for a truly leak‑proof seal. Our high‑quality borosilicate glass containers are designed specifically to work with our lids, giving you a reliable, premium experience every time.

Our lids transform into three unique positions. When stored, they collapse into the container, making stacking and nesting easy. In use, they sit flat like a regular lid—and when there's overflow, they expand to create extra space inside the container.
