  "whyPlastic": "A bare steel cup, a fired clay mug and a glass tumbler have nothing to hide. The plastic arrives with the add-ons. A sipping lid is polypropylene or silicone. Colored steel is powder-coated, which is a plastic skin, and brushed stainless is the bare one. Silicone sleeves and base pads add grip. \"Bamboo fiber\" cups are ground bamboo set in melamine resin. On a mug, the design can be acrylic paint sitting on top of the glaze instead of glass fired into it. Insulated tumblers add a gasket and a base pad to the list.",
