CD newbie here. We started out with a few different kinds, and have decided that Charlie Banana's are our favorite. So I've purchased several brand new, and then I purchased a lot of 12 pre-owned off of ebay. The seller stated that they were used in a large rotation for 6 months, and were selling because they preferred AIO.
I've received them, they look and smell fine. However they are not soft like the brand new CBs. The fleece is sort of pilly and the inserts are sort of 'crunchy' (like when a pre-fold is line-dried).
So my question is: is this normal wear and tear? Will all of my CB's look/feel like this in 6 months?
and is there a way to make them softer again?

Thanks for any and all input!
