Grosmimi PPSU Straw Cup (with Weighted Straw)

Grosmimi PPSU Weighted Straw Cup with Steel-Free One-Touch Cap is designed for babies and toddlers learning to drink independently. Made in Korea with a durable PPSU bottle body, it combines a soft silicone straw, weighted-straw system, easy-grip rotating handles and a one-touch flip cap for everyday use at home, daycare or on the go.

Why Parents Love It

• For 6 months+: designed to support the transition from bottle feeding to straw drinking.
• Weighted straw system: helps the straw follow the liquid as the cup tilts, making it easier to drink from different angles.
• Anti-leak “+” cut straw: the cross-cut silicone straw is designed to reduce leaking when the cup is not in use.
• Steel-free one-touch cap: flip-open design helps keep the straw covered between sips.
• Easy-grip handles: rotating dual handles are shaped for small hands.
• PPSU bottle body: lightweight, durable and heat-resistant for repeated everyday use.
• Fully detachable: parts separate for thorough cleaning.

Choose Your Design

200ml or 300ml?

Materials & Construction

• Bottle: PPSU
• Straw / teat: soft silicone
• Cap & handle components: child-use plastic and silicone components

How the Weighted Straw Works

The weighted straw is designed to move toward the liquid as the cup changes angle. This can help babies who are still learning to use a straw cup and makes the cup convenient for seated drinking and everyday movement.

Cleaning & Sterilization

• Disassemble all removable parts before cleaning.
• Wash the straw and silicone parts with a dedicated soft straw brush.
• Follow Grosmimi’s component-specific sterilization instructions for boiling, steam, UV, dishwasher or microwave sterilization.
• Do not microwave the One-Touch cap.
• Extended UV exposure or repeated dishwasher contact may cause printed designs to fade or wear over time.
• Allow all parts to dry completely before reassembly.

Care & Safety

• Always use under adult supervision.
• Inspect the silicone straw before each use and replace it at the first sign of damage or weakness.
• Do not use the straw teat as a pacifier.
• Check beverage temperature before serving.
• Keep away from fire and direct sunlight.
• Assemble all parts securely before use.
