What Happens Between a Bag Prototype and Production? Getting a bag prototype made is an important milestone, but there is still work to do before production. The prototype needs to be looked at as a real product. Does the shape work? Are the proportions right? Do the materials and hardware suit the design? Is the construction practical? Does the bag function the way it was intended? Answering these questions during sampling gives founders the opportunity to improve the product before committing to production. MOYA Studio works with founders on bag prototyping and sampling as part of the journey from concept toward production.
