This slim cousin to the Hi-Tec-C has a retractable feature that combines portability with perfection. It is a new edition and replaces the former Hi-Tec-C Knock S line. It has the same precision and clean flowing lines as the Hi-Tec-C, but comes in a smaller, sleeker design. It's the pen for those who love their Hi-Tec-Cs, and have always wished for a more compact design to carry around with them. Let go of the fear of losing caps and embrace the Hi-Tec-C Slim Knock!
