This is a Proyo take-apart, now commonly referred to as a Proyo 1, or Original Proyo. This type of Proyo was the last version they ever produced of the original style. The pog even features the character Maxx, the character featured on the Proyo 2.
Diffraction foil logo sides. The foil pattern varied. This Proyo is great condition, but notice the edges of the diffraction foil are lifting slightly from the backing, a common problem with this model.
Notice the hex shaped brass axle in the "Axle View", as well as the round brass nut used in the Proyo take-aparts. Proyo also made wooden axles for the take-apart, not pictured here.
Also, the Reverse View shows the back of the yo-yo first with, then without the diffraction pattern side cap. The "open" view shows the thumb nut used to take the yo-yo apart.
