2 Breeding sugar glider pairs

I have a male leucistic glider 3 years old paired with a female white faced glider also 3. They come with huge cage and all their supplies (wheel, bowls, toys , nesting box) . I also have a platinum male glider paired with a standard Grey female. All of their offspring have been white faced. They are also 3 years old and come with the same. I am listening to all offers on the pairs but please be reasonable. Also willing to trade for other exotics or saltwater aquarium. Thanks in advance!
