Says it began 2020Where Berwick-upon-Tweed, NorthumberlandNames Andrew Hardie, Liam Goward

Pith is a design and manufacturing studio specialising in paper materials for creators. Utilising the finest materials for maximum creative functionality with minimal environmental impact. Co-founders Andrew Hardie and Liam Goward launched Pith in 2020 with the vision of designing and manufacturing paper goods, drawing on three primary pillars: functionality, quality, and responsible production. Our products are conceptualised, developed, manufactured, and finished by hand under one roof in our beachside factory in Berwick-upon-Tweed. We are fortunate to have most of our production and assembly processes under one roof, which gives us greater control over our material selection and manufacturing methods. We run our machinery on renewable energy and reuse or recycle all our manufacturing waste.
