These have been my travel pocket notebooks for decades.  Brown cover, stitching binding, and paper pages are the highest quality.  I use them for all my foreign trips to pre recording references like exchange rates, climate date, metric and centigrade conversions, language tips, "identify the body" tips, insurance info, and quick glance itinerary.  Then during the trip I record favorite places to sleep, dine,etc.  Nice little pocket in the back of the journal for business cards.  Quicker for on the run reference than my phone, and doesn't have be recharged every night!
