I'm not sure where else you can buy things like the "Psychoanalytic Pencil Set" or the "The Philosopher's Jumper". The School of Life is an odd new brand/company/gift shop/school/media outlet from pop-writer Alain De Botton. They host a YouTube channel and their professed mission is to "develop emotional intelligence through culture". Some of their videos are quite good https://www.youtube.com/playlist?list=PLwxNMb28XmpdJpJzF2YRBnfmOva0HE0ZI and their gifts are uniquely useful for those with cleverish friends.
Skip the videos that aren't based on historical figures.
