I received the pliers around Feb 5, 2018 and they worked fine. When I used them today I noticed there were black marks on my hand. I used a wet paper towel to try to get the black off the pliers. The black was coming from between the nylon heads as well as the open areas of the pliers. The left plastic dipped handle came off as well. Not sure what the black marks are from but any open area had black on it. I would like to have the pliers replaced since they are defective but since I received the pliers in February I can't find out who to request a replacement from.
