Small batch production is a term to describe the production of a product in small quantities.  It's the opposite of large-scale mass production.  We craft our jewellery in small batches to help reduce our environmental footprint, and keep our waste to an absolute minimum.  By batch-making our jewellery, we maximise our efficiency to get the most out of our time and materials, reducing our waste even further.  It keeps our inventory low but avoids the risk of over-production.
