Drink & be merry - without worry. The glass is always half full. Forget cracked, hard-to-wash glasses or drinking wine from disposable plastic cups when out of the house. Instead, use these soft, flexible wine glasses at your backyard party or pack them in your backpack or suitcase for camping & travel. And here's another merry fact: Unlike flimsy plastic cups that add a horrible taste to your wine, the premium silicone used in these glasses retains all flavors and aromas of your best reds and whites. Premium Food-Grade Silicone This means it's nonstick, dishwasher safe, & an absolute breeze to clean. We recommend that you wash the glasses with soap & water before first use. If any silicone odor is still perceptible, simply wash them with baking soda and water. Unbreakable & Crack-Proof Another benefit of the squishy and virtually unbreakable material is that it never suffers from the cracks and fine lines that plague shatterproof glasses. These wine glasses are even safe in the microwave or oven, so they can be used for tea, etc. Ready to Take the Party Outdoors Easily pack your Ivation silicone wine glasses in any backpack or suitcase, and drink the day away at the beach, spa or pool. They're also ideal for camping and picnicking, and a godsend for wine enthusiasts who are clumsy with glassware. Elegant Stemless Design Just because you're doing away with the glass material doesn't mean you should miss out on any of the wine-drinking experience. The design features an elegant stemless look, the right curvature for aroma focus, and a solid feel in the hand. Set of Two 12-Ounce Glasses Each silicone wine glass holds a full 12 fluid ounces - or enough of your favorite libation to have a positive influence!
