A notebook that doesn't overwhelm your pocket!  These are small notebooks intended for breast pocket in a jacket or shirt pocket, hence their soft construction and slim size.  These are not for hip or pants pocket: there are more durable Molskine products for that.  These are intended for use as a "Note to self" book since they are not set up for page tear-outs.  I've been using these books for nearly twenty years and they deliver flawlessly.
