FAQs

Please read our FAQs page to find out more.

What is PPSU material?

The safe material, PPSU, is a lightweight yet highly durable and heat-resistant medical-grade material, ensuring safety without the risk of shattering like glass.

What is the difference between Stage 1 and Stage 2 straws?

Stage 1: The wall is softer, for beginners or non-chewers.

Stage 2: The wall is firmer, for children over 12 months who chew frequently.

All Grosmimi cups come with Stage 1 straw as default.

Which size of the cup should I choose?

For beginners with straw cups, the 200ml size is easier to handle. This size is suitable for water or small amounts of liquids. Consider a 300ml cup for larger drink quantities or milk and other beverages.

How to remove air from a straw cup?

To maximize functionality, utilize the air valve on the straw to release air from the cup. This essential feature regulates pressure balance, preventing leaks and adjusting to varying temperatures.

How often should I replace the silicone straw?

Recommended Replacement Schedule:

  • Silicone straws & mouthpieces: Every 2–3 months
  • PPSU bottle: Every 6–12 months
    (Replacement frequency may vary depending on use.)
