I put my clear stamps in cd cases. Some melted others didn't.  Can someone please explain why this happen?  They were stored this way in the winter in my craft room. So I don't think that they could have gotten too hot. Could it had been a reaction? They were cases that were put up in a box stored in an unused hallway.  I liked this way of storage but am afraid to store them that way again.

O.M.G.... bless you Kim. I hope you figure this out. I would freak out!

Holy smokes! Wow, Kim. If I were you, I would contact the company directly and see what they tell you. They may be able to replace them or at least explain.

"I know the plans that I have for you," says the Lord. "Plans to prosper you and not to harm you; plans to give you hope and a future."  Jeremiah 29:11

That's really weird...never heard of that happening before!  I store mine in page protectors and leave them on the plastic sheet that they come on. 

Hope you can get to the bottom of the problem!
