Entrance sleeve for penis pumps made of silicone. This sleeve is placed at the mouth of the tube (penis enlargement pump) and aims for the airtightness of the tube during the insertion of the penis into it. Most penis enlargement pump manufacturers use sleeves made of rubber, which results in them tearing or easily getting damaged during the insertion and removal of the penis from the tube.

Advantages over factory-made sleeves:

• Material: Medical Silicone (100% antibacterial, medically approved, skin-friendly).
• Sealing: Silicone offers better closure and ensures 100% airtightness.
• Masturbation: The sleeve is designed to simulate the feeling of insertion.
• Training: Can be used against premature ejaculation.
• Colors: Transparent and Gray.
