That’s because our tumblers are made from naturally occurring silica: a durable, non-toxic material that is flexible, durable, and can handle the heat. So go ahead, take this tough-as-nails tumbler anywhere and put it to the test - whether it's iced coffee, hydration on the go, a refreshing smoothie, or an extra thick milkshake, this 22oz unbreakable companion never takes a break so you never miss a moment. Silipints are safe for the microwave, dishwasher, freezer & more. They can hold hot & cold beverages, they're durable, eco-friendly and will never wear out. Avoid spills with the insane no-slip base. Silipints will not break, crack, chip, dent, fade or scratch. Silipints are safe & built to last. Silicone is made from materials that exist in abundance - the same materials that make up a huge percentage of the earth's crust. Silipints are made of 100% food-grade, platinum-cured silicone that is free of BPA, BPS and phthalates. EARTH-FRIENDLY: Silicone is made from common and very abundant materials and is completely sustainable and earth-friendly. Silicone tableware can replace plastic or paper and reduce waste. Switching to silicone cups, tumblers, bowls, and straws can help ease the strain on the earth and help you do your part to support a cleaner planet.

Our products are created to mimic glass shapes we already know and love, have finishes that get a little fancy, and come in colors to suit just about any decor.
