Parents using Philips AVENT natural glass baby bottles, these silicone sleeves are such a smart solution! You get three white sleeves that fit perfectly over your glass bottles to provide protection against drops and make them easier to hold. The premium silicone material is BPA-free and durable, so you don't have to worry about it breaking or fading with use. The bottom reinforcement design and extra-thick silicone provide better anti-fall protection, which is so important when little hands are involved. The hollow design is brilliant - it lets you see the bottle capacity marks clearly so you always know how much is left. They're anti-scalding too, which is great for protecting your hands when warming bottles. The elastic material makes them easy to put on and take off for cleaning. At about 2.76x2.76x2.56 inches, they're the perfect size for AVENT natural glass bottles. Having three means you can protect multiple bottles or have spares when others are being washed. They're cute, practical, and most importantly - they help prevent broken glass bottles which is every parent's nightmare. Just note that while they're compatible with Philips AVENT, this isn't an official Philips product.
