Tesoro's black and purple color scheme is visible front and center on the product packaging here, with an illustration of the keyboard on the front to go with the company and product name and its salient marketing features. This continues on the back and sides where we also see two double flaps that help keep the contents inside in place. A label on the side also alerts us to the particular permutation inside - a US (ANSI) layout keyboard with optical blue switches inside. Calling them mechanical switches in a misnomer of sorts here, but I think they just re-used the label template from previous keyboards.
Open the box and we see the keyboard itself in a plastic wrap, with the keyboard cable in the cardboard cutout compartment above. The keyboard is housed in a shaped cardboard piece such that it has the packaging cardboard all around it for protection - not the best I have seen, this setup will suffice provided the shipping packaging is done well. Under this compartment are the accessories Tesoro provides - a quick start guide in multiple languages (online copy here), a cheat sheet for the various onboard controls, and what looks like a metal ring-style keycap puller with inward-facing extensions, which are there for a reason. More on that on the next page. That's about it as far as accessories go!
