Purchased in 2022. Used from 5 months old to 1 year old. Used for two types of drinking: cup drinking practice from 5 months old, and straw drinking practice from 6 months old. The cup drinking part was only tried once as it wasn't used well. The straw part was used frequently. The straw part has discolored due to aging, so it will be sold without it. Capacity: 240ml
