The Neolid Twizz is a plastic 12 ounce cup made in France of light weight, waterproof and insulating plastic. So far that sounds pretty boring right? The interesting feature of this cup is the specially designed twisting lid that opens and closes with a twist. The lid opens like an iris or camera shutter and can be used with or without a straw, making it great for travel and kids. You can learn more about Twizz cups at neolid.com. They can be purchased from Newegg for is $16.80 or eBay for less than $10.
