Martingale medium weight 48 with 14 collar balck

 medium-sized martingale-style dog collar in black, with a 48 cm circumference and likely a 14 cm width or taper, designed to provide control and prevent escape for dogs, particularly those with narrow heads. The "medium weight" suggests it's built for durability and larger dogs, while the martingale design provides gentle, limited tightening to stop slips.
