This set of goggles has both eye pieces fitted out with 3 and 5 power magnifiers on each stem. The magnifiers really work. Leather is a beautiful deep chestnut brown and is treated with waxes and oils to make it supple and soft. The side strap attachments are "shotshell end" conchos for an added accent . Rim pieces are solid brass. This is a beautiful pair of goggles for the alchemist, savant or mad scientist!
