The RSVP International Endurance tray is built from 304-grade (18/8) stainless steel, offering a virtually indestructible chassis for the plastic-free kitchen. This material choice provides high corrosion resistance and superior thermal conductivity, allowing ice to freeze 20-30% faster than in silicone alternatives. The vintage-inspired lever-action system is designed to break the bond of the ice without requiring the torsional force of a standard plastic tray.
A practical reality of this mechanical design is the need for careful handling. Because ice-to-metal adhesion is quite strong, the lever mechanism can be subject to high tension. Users should allow the tray to "temper" at room temperature for 1-2 minutes before pulling the lever. This simple step protects the thin-gauge separator fins and handle rivets from permanent deformation or failure due to excessive torque.
This tray is a premium choice for those who want to avoid polymers and value a professional bar-grade aesthetic. It is fully dishwasher safe, though it does require more hand strength to operate than modern silicone-bottomed trays. It also has a higher noise level during the ice harvest. Overall, it is a sturdy, heirloom-style tool for those who appreciate traditional mechanical designs and neutral-tasting ice.
If you prefer a stainless steel option that produces round spheres instead of standard cubes, you may want to look at the Ecozoi 72-slot system.
