I have a lot of transparencies in archival polyethelyne Slide Guard pages I got from Light Impressions way back when. I store them in plastic boxes I got from Light Impressions, about 12x10x2" which have a hinged spine and top that folds over and fastens with two tabs on the opposite spine (also sold by LI as archival). I want to get a couple more of the boxes, but can't find them online anywhere. Anyone know what I'm talking about and where I can find them?
