The plaque is more like an advertising item, while the jetons are samples. MSK, while new to G2E and the American Market, is out of Korea and has been a staple in Korean casinos for the past 10 years (so they said). (Lyle, can you confirm?)

The representatives were very generous in releasing samples. All were freely given out for the asking! (I will post more scans later.)

Plastic/acrylic. Jetons are 43mm, in 5 colors.
