Boston Pump has been proven that a quality vacuum pump will stretch and enlarge tissues. Each pump is flared outward at the bottom and has a slight inward roll at the opening which acts as a built-in cock-ring and comfortable vacuum seal without messy gaskets.
Each cylinder contains a state-of-the-art connector/air valve. It allows the pump to be disconnected from the expansion cylinder while maintaining the exact pressure you choose. All cylinders are equipped with a growth indicator, which can mark your progress. |
