Question about Infinite crafting bags

I just read an article related to these bags

http://esoacademy.com/news/infinite-crafting-space-bags/

my question is: what happens if once they are available I subscribe to ESO PLUS and move all my crafting stuff to those infinite bags, then I fill my inventory again with other stuffs, but then after a while I decide I dont wanna pay a monthly fee any longer? what will happen to those crafting mats?
