Peak Silicone Ice Tray
Food-grade silicone ice tray with a steel-reinforced rim and a fitted silicone lid - flexible release with no plastic, landing at silicone-only.
Plastic-free verdict: Silicone only
The mold and the fitted lid are food-grade silicone; an internal steel frame stiffens the rim so it stays flat when carried. Water freezes against silicone, not plastic, and the flexible walls let you pop cubes out by flexing the silicone rather than twisting a rigid plastic tray. No conventional plastic in the contact path - so this is the silicone option for people who want flexible molds and accept silicone. Strict silicone-avoiders should use the stainless Onyx tray instead.

What it's made of
| Part | Material | Food contact |
|---|---|---|
| cube mold food-grade silicone; cubes release by flexing, no twist | Silicone | Yes |

A silicone ice tray that fixes the two annoyances of bare silicone molds: a steel frame runs through the rim so it stays rigid and level when you carry it full to the freezer, and a snap-on silicone lid keeps freezer odors out and lets you stack. The Peak (large-cube) version makes oversized cubes for cocktails; an everyday version makes standard cubes. Because the whole contact path is silicone rather than plastic, it lands at silicone-only - the flexible-mold counterpart to the all-steel Onyx lever tray. Dishwasher safe and BPA-free.
