Does anybody remember owning a pen that transformed into a robot? I had several back in the mid to late eighties. It was definitely not an official transformers product and was made by a third party company, something that you would have found in a dollar store. I remember that in pen mode it was flat, rectangular in shape and made up of primary colours such as blue, yellow, red and white. I can't find an image of it anywhere on the web, does anybody else remember having one of these?
