Where mass production is churning out machine made clones. In contrast Craft is the hand crafting of a single piece, where its imperfections are its qualities.
Mass Production
Mass Production is the production of large amounts of standardized products, including and especially on assembly lines. The concepts of mass production are applied to various kinds of products, from fluids and particulates handled in bulk (such as food, fuel, chemicals, and mined minerals) to discrete solid parts (such as fasteners) to assemblies of such parts (such as household appliances and automobiles). - Wikipedia
Craft
Craft is something handmade, meaning something made by an individual, rather than one made by mass production.
They both have their pros and cons.
