I have a couple of Cressi Big Eye Evolution masks. I recently broke off the retaining pin in one of the strap buckles. Where can I find replacement parts? I found one set of buckles on scuba.com but not the right color. I will get them but want a back up set of buckles for the next time they break. Also, stainless steel retaining pins would be a much stronger option. Anyone find a better retaining pin for the buckles on this mask? Thanks!
