Thank you soooo much for taking time to make a pic and answer me Chic Aeon ♥. I was doubting bcs i read in other topic that i wasnt able to put a no copy item with a copy one. But then i remind lot of folders i receive have nc and copy items inside so..
Anyways ty tons. I did a try with an alt and when i open the box, the gacha skin (nc nm) gone to the "objects" folder,, while the shapes (c nm nt) created a new folder called as how i named the box containing both things. So i had to open the nc nm item and introduce it inside the shapes folder first, then i packed all in a box that become as u said nc nm nt.
Have a nice day and again many thanks for the valuable help
