Do these dildos have customized colors?

Very few sex toy companies do custom stuff, and unless I'm really missing something Eden doesn't have any options for custom-made items. Your best bet to find out for certain would be to check out the manufacturer's website or email them.

I doubt it, unless you order several hundred of the same. Sometimes a manufacturer will do a custom exclusive color/style for a store.

I don't think so but they do have pretty neat color options.
