This all-in-one bundle includes the Grosmimi 10oz PPSU Straw Cup and a Stage 2 Straw Replacement Kit—perfectly paired to grow with your baby.

Crafted from medical-grade PPSU and platinum silicone, this set offers a leak-proof, mess-free experience with the same softness and safety trusted in baby bottle nipples. The Stage 2 straws are designed with firmer silicone for teething babies who tend to chew—making it a seamless upgrade when they're ready.

Each straw features a smooth, soft-touch finish to protect delicate gums and teeth, with a “+” cross-cut tip that keeps liquids in and spills out—even when shaken or dropped. Whether your baby prefers sipping upright or lying down, the 2-way system offers both options with or without the tube.

Bonus: The included straw brush keeps everything hygienic, while the adjustable 6-inch tubes can be trimmed to fit any cup height. Straws are also compatible with select wide-neck bottles.
