Now the same great Pre-Rotated 405 and Pre-Rotated 425 eyes you've enjoyed for years is available in a totally rimless style. There is no glass lip to hinder the insertion of nictitating membranes. The iris of the Pre-Rotated Rimless Eyes are rotated forward to allow for the white scleral band to appear around the perimeter. These eyes can be used for North American, Exotics as well as African animals.
