The Pigeon Baby Bottle Handles are designed specifically for Pigeon wide neck PPSU Baby Bottles of 8.1Oz. These handles are ergonomically crafted to fit comfortably in your baby's tiny hands, making it easier for them to hold their bottles independently. Installation is straightforward; simply align the handle's protrusions with the notches on the bottle's neck and slide it down until it clicks into place. Made from high-quality, heat-resistant plastic, these handles can be sterilized safely at temperatures up to 248°F (120°C), ensuring safety for both moms and babies. The design offers high compression strength and durability, allowing it to withstand the pulling and twisting that comes with a baby learning to grip.
