About the design:
This is a pair of the medallion style snake patterns that are a bit larger than the originals. They also have the Kanji symbol for “Fire” and “Water” in the medallion just behind each head. The “Fire” design is red, like embers and coils as flames sometimes do when leaping up into the sky. “Water”, on the other hand, flows sinuously back and forth as water flows down a stream.
