I am selling a S-rank Knuckle, the names i choose were Codys knuckle i know this lowers price but I'm selling the very cheap, the knuckle i will accept mag cells also, and other rare items i don't already have.
The mag cells i willing to trade for would be: Rappys beak, Heart of Kapu Kapu, and Chu Chu cell.
For PDs the Knuckle is 10-15.
