The cup provides measured small amounts of liquid (either 5cc or 10cc boluses) without the use of thickeners. Helps preserve the dignity of those who suffer from dysphagia or disorders associated with difficulties in swallowing. Cup has broad base to minimize tipping and spilling .Also allows for cleanup to be limited to one piece of dinnerware rather than several parts of other feeders. Easy to clean and institutional dishwasher safe. 5cc cup comes in blue,10cc cup comes in brown. Sorry,no color choices.
