Cognikids Honeycomb Bottle Cover (Pink) This is a grip cover for baby bottles, similar to an Oball, that can be used from around 4 months of age. There are no noticeable damages or stains. It has been cleaned thoroughly with dish soap. It will be shipped in a waterproof envelope with simple packaging. Since it is made of silicone and will not change shape, it will be shipped via Yu-packet Post, slightly compressed. Recommended for babies who want to drink by themselves or who are starting to show interest in holding things.
