How it works and why it helps

The PSX04 Dark uses a manual vacuum system to encourage blood flow into the penis, supporting a stronger, fuller erection whether you’re flaccid or already aroused. A tight, comfortable seal at the base helps create an effective vacuum, while the meter on the cylinder provides a visual cue of your progress. When you’re ready to finish, press the pressure release button for a controlled end to your session.

• Men seeking non-surgical enhancement and more confident, fuller erections.
• Solo sessions focused on understanding erection dynamics, or partnered play as part of a broader experience with compatible sleeves and accessories.

Care, safety, and responsible use

This is an adult intimate item that creates manual vacuum and is not a medical device. Perceived effects vary and are generally temporary. Use vacuum gradually and with moderate pressure; avoid prolonged use or excessive suction. Stop immediately if you experience pain, numbness, discoloration, or any abnormal symptoms, and seek medical advice if symptoms persist. For hygiene, remove the cylinder from the rubber, clean with a dedicated toy cleaner (N-507), and apply your favorite water-based lubricant (N-506) for a comfortable, ultra-wet night. The manufacturer/distributor disclaims liability for injuries from misuse, improper hygiene, or product modification.
