Thank you for viewing. This is the VARIVAS tip extension adapter, 80mm. I've used it with care about three times since I bought it a few years ago, so I think it's in good condition. I'm replacing my extension adapters, and since I have too many now, I've decided to organize them. Recently, I've carefully applied a graphene ceramic coating to all of my tips and equipment using a micro cloth and brush. I did everything at once. It took a tremendous amount of time... Even if it gets dirty, it can be easily wiped off, and I think it repels dirt and water well.
