Just saw the anime episodes this weekend with the rings stacked. Thought is was very cool.
For those who may not want to spend $50 for a single official ring, I use other rings for the original kinkeshi:
Off-brand 5x5 inch (4x4 pillar to pillar) ring plus a 6-sided cage: Less than $20
WWE Micro Maniax Action Figure Wrestling Ring Price varies
Around 8x8 (7x7 pillar to pillar)
The 4x4 is closer to scale but the 7x7 really gives me enough room to move around and have battle royals. I got it after I had issues fitting the guys in the 4x4.
The official one is almost 7 inches (probably 6 pillar to pillar) which is probably a perfect scale.
