To increase the marketing appeal of a product, it’s common practice for manufacturers to create different versions (or specs) of packaging and included documentation for use in different markets. The product itself is typically identical, regardless of the market it’s meant for.
On Massdrop, drops noted as "US Spec" contain products that were procured from a US distribution channel. Similarly, drops noted as "International Spec" contain products that were procured from a non-US distribution channel. If a warranty claim is needed for either of these products, members should contact Massdrop Support directly.
