Put a 35mm full frame transparency in the translucent cap, snap it shut, hold it up to the light, and you have a bright magnified image inside this handy viewer. Assorted colors.

They work fine! However, since Adorama requested that I answer a customer's question and then didn't allow my comment to be submitted (browser glitch?), this is the only way to assist the customer, presumably. The customer is wondering if he'll get the purple one as pictured. Well, maybe maybe not. I assumed I'd get the TEAL one that was pictured when I ordered several, but I got four black ones and a white one. I queried the "colors" I got, and was told that no one has any choice. So I'm STILL not happy about that.
Fully met my expectations - were used in a gallery exhibition in England and went down a 'storm'. The audience loved them and the hot topic was - "where did you get those viewers?" Great choice of colours too!
