PLEASE NOTE THAT WE CAN INSTALL LENSES OF DIFFERENT COLORS AS PER YOUR REQUEST (CLEAR, GREEN, ORANGE, GRAY, BLUE, RED, BROWN). ____________________________________________________________ Good day to you, Ladies and Gentlemen. Our shop – “Mann & Co” – proudly presents a pair of solid brass goggles. These goggles are 100% handcrafted – unlike most of the goggles, that you see on Etsy, these aren’t made from spraypainted plastic welding\motorcycling\swimming goggles,brass plumbing parts, etc… All of our goggles are made from scratch. And when we say it – we mean it. Here is the list, that provides you with all the required information about this fine product and it's properties: Frames – made of solid brass. Outer diameter of the frames - 52mm, inner diameter 42mm. Lenses – made of 3mm perspex. This type of perspex provides UV protection. Oculars – made of 2mm veg-tanned leather, finished with Feibing's "Atom Wax" to achieve additional smoothness and rich gloss. Padding rims - made of soft 1mm calfskin. The padding is handstitched to the oculars with waxed polyester thread. Strap – made of 2mm veg-tanned leather, finished with Feibing's "Atom Wax". The strap are 1.55 cm wide and long enough to fit even the largest head sizes and being worn over aviator caps or cylinder hats. Strap buckle and loop – classic "roll buckles" made of steel and anodized with brass. Very durable. Screws, nuts and studs – all solid brass. Threading is standard 1\8". These brass goggles are fully wearable and will fit perfectly. ___________________________________________________________ WE SHIP WORLDWIDE We ship via Express Mail Service (EMS).

Practically, all our goggles are made of brass and leather (sometimes using mild steel, tin or copper rivets) – no "faux leather", no synthetics or plastic...The only un-authentic parts are perspex lenses and polyester threads – and this is only for the reasons of safety and reliability – we do not want shards of broken glass getting into the eyes of our clients, nor we want ocular padding falling apart after two or three years of usage. That’s why, it is not glass lenses and cotton thread, but perspex and polyester. In this particular design the lenses can't be swapped - they are tightly secured in the frames. The frames are very solid, strong and a bit heavy. The lenses are rather thick, and if broken (that is extremely improbable), they doesn’t shatter like glass. The frames can withstand almost any blow, and, if not shot with a gun, put into a car crasher or thrown into a melting pot (highly unrecommended!!) will likely serve you for a lifetime. However, these goggles are a novelty item after all, so, we do not recommend using them while working with acids or other hazardous materials.
