How I store mine is completely the opposite of Lush's ethos. They're all in plastic Ziploc bags. I have a large bag full of Creamy Candy, another full of Gold Slumber bombs, etc. Each is labeled with what's in it. I do the same for the soaps, melts, and massage bars. From there, they're all in the larger, under bed, plastic tubs. I will say that when the plastic bag is empty, I use them for a different product. I've not had any issues with scents leaching into other products or any sort of molding.
