The JBoa by Velv’Or is a fully adjustable penis ring designed to constrict the penis at its base resulting in super hard, longer-lasting erections, as well as euphoric ejaculations.

To really enjoy the benefits of the JBoa it should be worn as close to the body as possible.

The closer it is to the base of the penis the better the effect will be.

The erection will be fuller and harder when the JBoa is worn on the correct spot.

The wearer can achieve this positioning by pushing the tightened lasso toward their body with their thumbs.

 JBoa can e enjoyed during foreplay, intercourse, masturbation, edging, etc.
