Put it with your keys on a key ring,
hang it on a chain / rope,
or lay it on a flat surface.
The hole for the chain / ring is 4.5 mm wide in diameter.
To be fair, in the renders, I simulated the printing lines you may have with steel, bronze and gold.
The price includes shipping + shipping taxes, but not local taxes that may apply in your country upon reception.
