Glass Container with Silicone-Framed Lid
Borosilicate glass container whose lid is a glass panel in a silicone frame - so the lid is plastic-free too, unlike the plastic snap lids on most "glass" containers.
Plastic-free verdict: Silicone only
The container is borosilicate glass and, crucially, so is the lid - a glass panel held in a silicone frame that seals with a silicone gasket. Nothing but glass touches food, and the only non-glass material anywhere is the silicone lid frame/seal. This closes the loophole in most glass storage sets, whose lids are plastic.

What it's made of
| Part | Material | Food contact |
|---|---|---|
| container body | Borosilicate Glass | Yes |
| lid panel | Borosilicate Glass | Yes |
| lid frame and gasket silicone frame holds the glass lid panel and forms the airtight seal | Silicone | Yes |
Included because it fixes the single most common food-storage compromise: the plastic lid. Most "glass" storage sets (including mainstream Pyrex/Glasslock) seal with a plastic snap lid that contacts steam and food. Urban Green's lid is a glass panel in a silicone frame, so the only non-glass material is silicone. Oven- and freezer-capable glass; airtight and leak-resistant.
Pros
- Glass lid, not plastic - the whole point
- Borosilicate handles oven and freezer
- Airtight silicone seal; genuinely leak-resistant
Cons
- Silicone frame/gasket (not for strict zero-silicone users)
- Heavier and pricier than plastic-lidded glass sets
- Glass lid is breakable
