Size Matters Vaginal Pump 3.8" Small Cup by XR

Discover a compact approach to intimate suction stimulation with the Size Matters Vaginal Pump 3.8" Small Cup by XR Brands. Featuring a small ergonomic suction cylinder, medicine-ball-style hand pump, flexible no-kink hose, quick-release valve, and airlock pressure-retention system, this pink vaginal pump kit offers adjustable external vulvar stimulation.

Designed for use over the external vulvar area, the Size Matters Small Cup Vaginal Pump uses manually generated vacuum pressure to create a temporary sensation of fullness. Gentle suction may temporarily increase blood flow and swelling in the labial tissues, creating a feeling of pressure and heightened sensitivity. Individual experiences vary.

The small ergonomic cylinder measures 3.85 inches in length, 2.8 inches in width, and 2 inches in depth. Its compact dimensions provide a useful option for customers seeking a smaller suction cup design.

The included medicine-ball-style squeeze pump allows users to gradually create suction by hand. Connected to the cylinder by a 10.25-inch no-kink hose, the pump offers convenient manual operation without requiring batteries or charging.

A standout feature is the airlock release system, which the manufacturer describes as allowing the cylinder to retain pressure after the hand pump and connecting hose are removed. This provides an additional positioning option, but the cylinder should never be left attached without supervision or the ability to release suction promptly.

For added control, the kit also features a quick-release valve to help reduce vacuum pressure when needed. Always confirm the release mechanism works before applying suction.

Constructed from polycarbonate, PVC, and rubber, the Size Matters Small Cup Vaginal Pump combines a structured cylinder with flexible pumping components. Its pink colour gives the kit a distinctive appearance.

Suitable for adults interested in exploring external vulvar pumping, this manual system features straightforward controls for gradual pressure adjustment. Begin with minimal suction and avoid excessive pressure, prolonged wear, or attempts to achieve a particular amount of swelling.

Any increase in labial fullness is generally temporary. The product is not intended to permanently enlarge genital tissue or provide medical treatment.

With its compact pink cylinder, hand-operated pump, no-kink hose, and airlock system, the Size Matters Vaginal Pump 3.8" Small Cup by XR combines a smaller cup design with convenient manual suction controls.
