The PUD (''Penile Uncircumcising Device'', left)<ref>Picture courtesy of American Bodycrafters Inc., inventor und patent holder of the PUD</ref> and the ''Foreballs'' (right)<ref>Picture courtesy of R. Wayne Griffiths, M.S., M.Ed., Cofounder and Executive Director of NORM www.norm.org</ref> are weights. With the first, the [[Glans penis|glans]] in positioned in a hollow at the upper side, the reserve [[skin]] pulled over the rim and secured with tape at the narrow point. This is the only device on this list that allows for [[urination ]] while worn, since it has a tube bored through the centre from the hollow to the lower end. Using the foreballs, the smaller ball is placed against the [[Glans penis|glans]], the [[foreskin]] pulled over it and secured with tape at the connection bar. This method is based on gravity to generate the needed drag, and therefore is not very effective if worn under tight fitting clothing or when sitting. The foreballs device is no longer in production.
