I don't remember anyone on here talking about a plug kit but I have one that I like. Got it at a yard sale along with a box of Bubba ropes and soft shackles ..it was buried in the bottom.
Seems nice compared to the cheapo plastic ones.
Aluminum handles. Has pliers, razor blade, valve tool, couple stems, and lube. I added glue and patches, but instructions say not to use glue with their plugs.
Edit: didn't realize how much it cost!
