Sooooo many colorrrrrs!
Dr. Inkenstein recently purchased a bunch of these off fleabay. They're so cute I laugh every time I pick one up. Yes, they have the famed logo of Big Brown. They probably date from the 1980s or 90s. NO idea of their true history, though.
They are comfortable enough to hold, and seem to be of decent build quality. Dr. Inkenstein will use these as travel companions and diva-y ink testers. And maybe give a couple away.
