PAW WING S size 4 sheets x 5 sets (20 sheets) Black Purchased a year and a half ago, opened but unused. The stickers are unused. Would you like to try them? Non-slip pads to protect dog's paws. For dogs whose hind legs are weakening and slipping. These are applied to the paw pads. These really helped our dog! Feel free to ask if you have any questions ♪
