cyanotype storage?

I'm looking for sleeves and storage boxes for cyanotype prints. I know I need "unbuffered" materials for storage, but not sure where to get these. I'm looked through the Light Impressions catalog and have found unbuffered tissue and paper, but not sleeves or boxes. Any suggestions? How do others store cyanotype prints?
