The ProtoBag Studio blog publishes practical guides on bag sampling, OEM production, and finding the right manufacturing partner. Written for independent designers, side-hustle founders, indie brand owners, and brand owners switching factories — across Berlin, Munich, Amsterdam, Copenhagen, Stockholm, London, Paris, Milan, and beyond.
Featured article: How to find a custom bag manufacturer in Europe. A 2026 founder's guide covering where to look, what MOQ to expect, how to vet factories without flying anywhere, and what a useful first reply looks like. Read the full article.
Coming articles cover MOQ explained from 200 to 3,000 pieces, tech packs for bags, the practical difference between sampling and OEM production, and material decisions for first-time bag founders.
All articles draw from real client projects — sampling reviews, factory vetting notes, MOQ negotiations, tech pack feedback, and material consultations done with growing brands across Europe and North America.
