Keiran Copper’s first bi-metal yo-yo…
Please note: this yo-yo is made with genuine copper.
Over time, copper naturally develops a patina;
a greenish or brownish surface layer that forms through exposure to air, moisture, and handling. This is a natural and often desirable feature. If you prefer to keep the original shine, you can clean it occasionally using a mix of lemon juice and salt.
