I've had some vacuum tubes for a long while now and finally figured out a good way to use them. I wanted these to look like "powered" goggles with the coils running from the vacuum tubes to the lenses. As with all my goggles these also have a quick release strap on the left side. These are all solid brass, hand stitched, and hand dyed vegetable tanned leather. Unlike goggles made from plumbing parts, these are not heavy. In fact, they weight just a few ounces.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
