aluminum cupcake cups

They’re made from aluminum (aluminum foil), commonly described as sturdy, food‑grade aluminum foil suitable for food use.

Listings show a range of physical sizes—for example, roughly 2.68" x 1.57" down to about 1.10" x 0.59"—and at least one product lists a capacity of about 5 oz (120 ml).

Many listings sell these cups in packs of 50. Pack quantities can vary by product, so check the product listing for exact counts.

Some sets include extras such as clear plastic lids and individually wrapped spoons. For example, one product lists 50 clear lids and 50 wrapped spoons included with 50 cups.

Many cups are described as disposable, but some can be cleaned and reused. You can throw them away after use or wash them gently for another use if the product and condition allow.

The clear plastic lids are designed to snap on and fit securely, but they aren’t heat‑resistant. Wait until treats cool before attaching lids, and avoid packing hot items tightly together to prevent lids from sticking.

They’re described as made from thick, sturdy, food‑grade aluminum foil and marketed as greaseproof, nonstick, and high‑heat resistant.
