The Airabc 4-pack features a hybrid construction of rigid polypropylene and silicone-injected wells, designed to solve the "floppy tray" issue common with all-silicone models. This design provides structural rigidity during transport while allowing for the "easy-release" of individual cubes. The silicone used in the 14-cube wells meets LFGB standards, which is a stricter requirement than standard FDA guidelines regarding material purity.
The included lids allow for stable 4-high vertical stacking, which is highly practical for organizing a busy freezer. However, these lids are not 100% airtight and are meant for stacking and odor protection rather than for leak prevention if the tray is tilted. To avoid the lid freezing to the ice, users should be careful not to overfill the wells past the internal shoulder line.
Over time, silicone can absorb some freezer odors, so monthly deep cleaning is recommended to maintain neutral-tasting ice. Additionally, users in hard-water areas may notice mineral buildup in the wells, which can be managed with a simple vinegar rinse. This set is a high-utility choice for those who need a consistent supply of standard ice cubes and value a sturdy, stackable design.
If you are looking for larger cubes for slow-melting spirits, the Excnorm Large Square Molds provide a more specialized option.
