Find the maker of a product

my favourite notebook that was made by paperchase I cannot get now. The brand is called Agenzion and was by paper chase - they did them in all sorts of colours and sizes and I desperately would like to find out who makes them - their contact details. Were they just made for Paperchase or can I order some... It looks as if they are made in china - I want to know also costs etc and if I can rebrand them and anything more you can help with - can you help?
