A key chain with a logo on unpainted brass and a dummy key with a vintage key motif.
The brass becomes dull due to aging, and you can enjoy the texture like real vintage.

Note:
Since it has no paint finish, product might darken overtime. Please enjoy the secular variation. 
Brass is soft and easily deformed, so it may be deformed when strong force is applied. Be careful when hanging heavy objects. 
Since it is a product that makes use of the texture of handmade products, there may be uneven markings.
