The reflective leash is a bit thinner than I thought, but it serves the purpose of a leash. Have not had it outside to see how well the reflective thread works, but decided after I had ordered the reflective thread in the leash, I really didn't need that feature as I will always be holding the leash, so I will know where the dog is. I would not waste my money for the reflective thread add on. I would recommend this leash to go with the engraved collar. The collars I chose match perfectly.
