A rather stylish keychain...
This one is just the Sonic Forces logo...but it manages to be super stylish due to the material and craftsmanship. The metal is pewter-tone, but probably stainless steel for sturdiness. The logo is done in layers/somewhat-relief, with patina applied to darken the lower parts further/contrast.

It doesn't need color, because it uses texture to convey the detail of the stars, words, and their background. Look at the 'ragged' edges on the strips under the words, and the 'wrinkle' texture inside the stars. The Japanese text under it spells out "Sonic" and then probably their word for "Forces" (so, basically just a direct translation on itself) This is actually really nice, something good and different too...plus, it looks quite quality.
