Schlage SC4 Keyway (Same as SC1)
Lishis are only able to be returned if they are unused. These tools are all inspected before being shipped to the end user for quality assurance. Lishis are precision tools and if used with too much force they can easily bend the picking arm.
If a picking tip is bent or broken in use, the tool is not eligible for a refund or replacement. A photograph will be required for all exchanges or returns and they will be examined before returns are processed.
