To the op: This is a very good question! And I have no idea, also seems like another one of those 'grey' areas because paint for example if you buy it in the mog station you can't turn around & sell it but yet it could technically be gifted while purchasing. Every time I call SE customer support they usually address my questions but on occasion they have no idea or it's a 'grey' area they tell me to ask support in game so that I can ask the gm directly, honestly I think that's your best option is to ask a gm, because some things they say nothing about while other things well I'm sure you get the picture.
