The Big Man air pump offers quick and safe penis enlargement with a total tube length of 22 cm, ideal for most penis sizes.

Pump features:

• Total device length: 25 centimeters
• Diameter: 7 centimeters
• Material: Transparent hard plastic, Silicone
• Easy to wash
• Use with water-based lubricant

Before use, disinfect the pump by washing it with antibacterial soap and warm water. For best results, use the pump with a sexual lubricant, always choosing the appropriate pressure to avoid injury to the penis.

After use, clean the pump immediately with warm water and soap, let it air dry, and avoid direct sunlight. Store it in a cool, dry, and dust-free place.

The negative pressure/suction helps relax the smooth muscle cells, which allows the sponge to swell. Once the sponge expands, arterial blood flows in to accelerate hyperemia and increase penis hardness.
