Cups in this selection are made from paper, stoneware, and stainless steel. Lids are commonly polypropylene (a type of plastic) or stoneware, and some sets include removable straw lids.
Many lids are described as splash‑proof or leak‑resistant. Some flip or threaded lids are advertised as leak‑proof when closed, and reviewer feedback frequently highlights good spill resistance.
