Listings predominantly identify silicone as the material, though some descriptions list plastic. Product pages most often show “Material: Silicone,” with a smaller number indicating plastic.
One listing specifies each cavity as 2.1 inches by 0.82 inches, and several listings list a per-cavity volume of about 1 ounce.
Molds are described as flexible and non-stick for easy release, with smooth surfaces that rinse clean or are dishwasher-safe.
Multiple listings describe the molds as reusable and durable, noting they retain their shape over time for repeated use.
Listings advise rinsing or using the dishwasher for cleaning, using a cookie sheet for stability when moving molds in and out of the oven, and folding flexible silicone for space-saving storage.
