Custom crafted to the highest standards, these goggles are patterned after alchemists' goggles of old. Fully functional magnifiers swivel over one eye piece (let me know which eye you want the magnifiers on!) so you really can see small things up close. The magnifiers are 3 power, and work at about four to five inches away singly and about an inch away when used together. Brass rims and rivets, and supple brown chap leather complete the look. For the steampunk naturalist, savant or scientist! Clockwork pieces vary - they will be watch movements or clock wheels. If you want to know exactly what I have in stock i will be glad to provide photos.
