Bedding Container?

Hi! So soon I will be moving into an apartment with my chinchilla's (4). I am switching them back to bedding as my boys decided to start eating their fleece :impatient:



I was wondering how everyone stores their bedding? I would like to place it in a rolling container so I can move it easily to each cage (I have 2 critter nations).



I have two bins already for hay and food but I need something bigger for the bedding!



Thank you :)
