Horizon is another division of Hermes that has more creative freedom due to how it creates custom or small projects. Horizon doesn’t only produce customer custom orders, but also is in charge of creating special, limited pieces in some cases for store openings (the latest Homage a Kelly Kelly for Maison Madison was created by Horizon). Horizon does edit Kellys and Birkins as seen with that edition as well as the Kelly Lakis (a Horizon project for Lakis Gavalas). A friend of mine has a horizon Birkin 25cm that has a custom color and lining, which was part of a larger horizon project. There really isn’t any limit, but they do not want people to use Horizon as a backdoor to quota bags. One can bespoke order a quota bag if they are established clients whose wish can not be fulfilled by the limitations of special orders.
The RMS suitcases are also a project by Horizon as well as all the bicycles, skateboards, surfboards, surfing gear, and fishing gear. These items are now available to purchase in stores like the St Louis disco ball which was a customer’s project that has been commercialized now. The reason why a completely custom item like a bag is so costly is that one must pay for the design team, renderings, prototypes, and all the behind the scenes of creating any item from zero, which can include travel of the team in some cases. For projects from scratch, it’s more like 10x comparable, commercial price.
