Eco-friendly party planning just got easier with these aluminum cups! They have basically everything going for them: dishwasher safe, reusable, infinitely recyclable, lightweight enough to take to a picnic, easy to store, affordable...and they actually keep your drink colder than plastic! Invest in a set that you reuse—and if you can't collect them for reuse, make sure folks know they can be recycled with alumnium cans. Choose from a pack of 12 or 24 cups. Made in Rome, Georgia. Note that the aluminum is coated with a food-safe liner (just like aluminum cans). Washing them (particularly in the dishwasher) will break down this liner over time, at which point there is some risk of the cups leaching aluminum. The manufacturer's website recommends using the cups up to 10 times, then recycling.
