Cash item transfer

So i've decided on a look for my Demon Avenger:


The problem is, the overall and the wings I got recently from Premium Surprise Style Boxes on my Kanna, they are still tradeable, but i'm worried about the trading process and would like some clarification:

So my Kanna does a "cash item trade" with a friend, and they trade it to my Demon Avenger right? Is it that simple? or is there something preventing this? are there any rules that i'm not aware of?

Probably a stupid question I know, but it's just for peace of mind. Thanks!

I did that with a few items before and there was no problem.

Yeah, the only issue is either having a way to run a second MS yourself or a friend you can trust to hold the things while you switch characters.
