  "whyPlastic": "The shaker most people own is a plastic cup with a plastic lid and a wire whisk ball. Steel and glass versions exist, but the plastic tends to hide in the lid: a screw cap, a flip top, a spout, a carry loop. Then there's the gasket, which is usually silicone, and the whisk, which is sometimes a plastic agitator that snaps into the lid. A steel or glass body with a steel lid and a whisk ball made of wire is the real target. What to watch is the small stuff: a powder-coated or painted body, a lid that's steel on the outside and plastic inside, and a silicone sleeve around the glass.",
  "whatToCheck": [
    "Body: stainless steel or glass, and is the outside painted or powder-coated?",
    "Lid: steel, wood or bamboo, or plastic with a steel look?",
    "Whisk: a wire ball or a steel insert, or a plastic agitator?",
    "Seal: natural rubber or silicone, and is it named?",
    "Grip or sleeve: any silicone or plastic wrap around the body?"
