Expansion rather than a fixed shape
An anal balloon increases in volume after insertion. The pressure and maximum dimensions stated for the model are more important than how small it appears when deflated.
Pump in small steps
Use short pump movements and pause between them to assess the pressure. Stop immediately when the sensation becomes uncomfortable.
Release control must stay accessible
Keep the hose and release valve within easy reach throughout use. Never kink or block the line needed to reduce pressure.
Deflate, remove and clean
Release the air completely before removal. Inspect the balloon, seams and hose before each use and clean as instructed without damaging the system.
