This is a classic STS buckle, in production since 2003. It is a one liner, and actual little door knocker- yes the ring moves. Mounted on a hand made steel buckle, the brass shines on the mellow blackened steel.
Perfect for leos, those with a sense of humor, and anyone who likes lions.
The buckle fits a 1.5" belt, sold separately on my store.
Shown here on an ochre belt.
