The Richell S3 straw is an official accessory specially made for the T.L.I Richell S3 training cup — one of the well-known training cup lines from Japan, trusted by many Vietnamese mothers for babies from 7 months old and up. This product helps replace old, damaged, or unhygienic straws, maintaining the cup’s performance as if new.
Reasons to replace the straw periodically:
- Ensure hygiene and health safety for your baby
- Prevent issues such as clogged, cracked, leaking straws or loss of anti-choking function
- Recommended: replace the straw every 2–3 months or sooner if there are signs of damage
Usage notes:
- Clean the straw before and after each use with warm water or a specialized bottle-cleaning solution
- Do not use strong detergents or hard brushes that may tear or wear the straw
- Do not use in the microwave
