Dog Collar (22-30cm) and Leash Set in Orange for Small Dogs

I purchased this collar for my dog, but I'm using a different one, so it's practically unused, only tried on indoors.
The leash is brand new and unused, with a reflective strip for safety in dark areas. The length, including the handle, is 87cm as shown in the photo.

I'm decluttering and selling it because it feels like a waste not to have it used by someone.

Please refrain from purchasing if you are sensitive about items that have been stored at home.
