this is a new (no tags but I have to list it as nwt on poshmark) dog leash that attaches to your bike. still unused with the instruction sheet and a training clicker. you clamp the base on the seat post of your bike and it sticks out to the side. the leash section has some elastic. I always make deals on bundles! Due to nuances in lighting, camera capabilities, and viewing screens, colors may be different than they appear. Please check measurements before purchase. All measurements are approximate. I have a pet friendly house so I try to use hair rollers on all items before storing, and I check before shipping. Despite my best attempts, I know there are going to be escapes, so be advised if you have allergies.
