Skins/Weapon Camos/ Trinkets question

I have been using all the extra stuff like skins and what not on my main Zane. I realized that some of the have been for other classes once I noticed that they were not appearing in the customization machine. Are they account wide? Like if I use the on Zane, when I make a siren, I’ll have access to the skins that I use on zane? Also, is the storage account wide as well?

The storage is global. Skins are case by case. Some are global while most I found were individual.

Well that sucks about the skins… My vault is already full expanded and full already :confused: Wish skins and camos and stuff were account wide
