How it works for you

By creating a controlled vacuum, the PSX04 Crystal draws blood toward the penis, supporting stronger, fuller erections. When you’re ready to finish, the pressure release button ensures a quick, comfortable conclusion. The design prioritizes a secure, comfortable seal at the base, which helps maintain effective suction without discomfort—even when used during longer sessions.

Who benefits from this pump

Ideal for men seeking a practical, non-prescription solution to enhance erectile quality and shaft girth. It’s a good fit for solo sessions focused on personal confidence, and for couples looking to explore new sensations and dynamics together. If you appreciate hands-on control, clear progress feedback, and modular customization with compatible accessories, the PSX04 Crystal is a compelling choice.

Use cases and practical tips

Use cases include pre-activity warm-ups to boost arousal, solo sessions to explore pressure and sensation, or shared play to add variety. For best results:

• Start with low suction and gradually increase to a comfortable level.
• Monitor the progress with the built-in meter to understand what intensity you respond to best.
• Pair with a water-based lubricant for an even tighter seal and smoother operation.
• Clean after use with a dedicated toy cleaner (N-507) and dry thoroughly before storage.

Materials, care, and safety

The PSX04 Crystal features a waterproof assembly with silicone and ABS components, designed for repeated use. It’s phthalate-free and straightforward to clean—simply remove the cylinder from the seal, wash, rinse, and air dry. Use a water-based lubricant (N-506) to enhance comfort during sessions.
