You get: ♥️ New xs/s/m adjustable collar that’s lite Blue Reflective with bell & reflective blue leash. The distribution company I purchased these from didn’t say what size these are other than “one-size”. To help you determine if the collar will fit your dog or cat I added reviews from other people who purchased this set. Basically it does fit all domestic cats, if your dog can wear a cat collar, or can almost wear a cat caller, it could probably where the collar in this set. It’s adjustable and adjustable making it smaller it fits my 4 pound chihuahua, but there is plenty still to open it larger to fit a bigger pet. A thin medium size dog would be the biggest size dog to try it on and I wouldn’t go with pets under 3.5 pounds. I ship everything the same day it’s purchased. Only $4.99 priority shipping fee. I ship everything in the special usps priority shipping packaging so that all the postal workers will im immediately see your package and keep it moving.
