Duped Sojs

I have a question about duped sojs...

Would the duped sojs be the same "icon"? By "icon", I mean the different forms sojs come in: the red swirly things, the round blue ring, etc...

For example, if i see 10 sojs of the same kind (for example: the red one), would they be duped? And if someone offers a variety of soj rings with different "icons", would there be a chanced that he duped them all at once?

Basically, my question is: when the sojs were duped, could you only dupe one kind of soj at once? Like if you sold a red soj, would you be able to buy both red, blue, etc sojs at akara?

~sry if this is too long/confusing Thx in advance
