Dr. Brown's Natural Flow® Options+TM 広口ガラスボトル用シリコンスリーブ

The grip on these sleeves is fantastic—my baby can finally hold her bottle without it sliding out of her hands. They pop off easily for washing, which I appreciate since milk residue gets everywhere.

My little one kept slipping out of bare glass bottles, so these sleeves are a lifesaver—the 100% silicone is removable, which makes cleaning super easy. They’re grippy enough that I can hold the bottle confidently with one hand while juggling everything else.

The silicone is a lot thicker and grippier than I expected, so even with wet hands I can hold the bottle securely. My baby's dropped it on tile a few times now and the glass underneath has survived every single time.
