Keiran Cooper’s bimetal signature, built from tumbled 7075 aluminum with genuine copper rims. Copper has greater density than stainless steel, providing massive rim weight within a compact frame for exceptional spin stability through long combos. The copper naturally develops a patina over time through exposure to air, moisture, and handling — each yo-yo becomes unique with use. Can be cleaned with lemon juice and salt to restore the original shine.
