Osbon Large Insert
$19.99
For use with the Osbon Esteem and Osbon Classic Models
The large custom insert is an optional accessory that narrows the cylinder chamber to provide a better vacuum when needed based on penis size. Rounded outside edges provide a comfortable fit against the body. The Large Insert is included in the Osbon Esteem Manual, Osbon Esteem Automatic and Osbon ErecAid Classic systems. If you are using this large insert and still needing to fill space at the base of the cylinder, consider trying the small insert.
