Stubborn Mule is primarily an OEM/Variance machine shop. This means our business is to provide other companies with high quality parts through the means of work orders and contracts. We work with large quantity orders, specializing in bulk production and variance work. Our business is not designed to provide the average consumer with a product direct from us, but rather provide another company with a product they can sell to the general market.

If you are looking to have a product made from your own design, simply send us an email. Let us know what you're looking to achieve and we can schedule a phone call or conference to get you started. Minimum order quantity for any OEM/Variance work is set at 25 units of a similar item.
