Caraway Glass Food Storage Set
Caraway
Glass Food Storage Set
Glass containers and glass lids with a food-grade silicone seal. Mostly glass and independently lab-tested, but the silicone seal is a synthetic, so a low-plastic 1 rather than fully plastic-free.
Borosilicate glass containers with glass lids, so no plastic touches food. Stackable and oven-safe, independently lab-tested for toxic substances.

What's inside
Glass food storage where the containers are borosilicate glass and the lids are glass with a BPA-free silicone seal, so no petroleum plastic touches food. The set is independently lab-tested for toxic substances.
| Part | Material |
|---|---|

| Lids | Glass with a BPA-free silicone seal |
Free of PFAS, BPA, phthalates, plastic food-contact
- Packaging
- Recyclable glass; the silicone seal is durable but not curbside recyclable
- Microplastics
- The borosilicate glass containers and lids are inert and shed nothing. The lid gasket is food-grade silicone, a synthetic that is not a petroleum plastic and sheds far less than plastic, though it can release trace particles or siloxanes under heat or with age.
