Frequently Asked Questions

We are a custom manufacturer and fabricator, specializing in prototyping, one-off orders, and small volume. We offer CNC machining, lathe, milling, turning, and many other services. The majority of our work is in small to medium sized metals and plastics, though we welcome quotes of any nature.

Our home office and main factory are located in Tokyo, Japan. Orders will ship from this location. We have a secondary factory in Kanagawa, Japan. Our US sales office is located in Milwaukee, WI. Customer service, payments, and other inquires and handled through this office. Poke through the About Us section for more details!

While we still have to obey the laws of physics, we accept orders from anywhere in the world. Shipping will always be at the mercy of couriers, but we'll work with you to provide the most suitable solution. Due to COVID-19, there are some restrictions on shipping methods, destinations, etc., which are out of our control. We will do our best to make sure we are providing you with a sensible and fitting shipping method. Currently, all orders ship from Tokyo, Japan to eligible locations, typically through Pegasus or FedEx.

Generally speaking, there is no minimum quantity, though this does depend on what materials and production methods are being used. For example, machining from raw stock of common materials usually means we can cut a quantity of one or two no problem. Injection molding requires a mold to be produced on top of the actual finished product, so sometimes, this isn't ideal for small volume. We'll do our best to provide you with what you need in a method that is appropriate.

Because we focus on the prototype stage of the process, we do not carry any certifications. However with the right demand, it's something we may pursue in the future.

While our focus is on small volume orders, we are certainly open to large volume orders. However, we do not handle repeat production orders. Please note we do not offer packaging services, nor do we handle direct to shelf distribution.
