3 Ikelite ports for sale. I just bought them as part of a set and need to sell them to buy the correct port for my lens. The seller claims they were either never used or only used a few times in freshwater. They appear brand new with no scratches, blemished, etc. If interested I can send pictures as well as the sellers ebay page that I bought them from.
