These are fashion glasses from Lunettes du Jura! They're designed to rest on your nose! (See photo 5) Here's a picture of them being worn! I bought them 4 years ago for about 60,000 yen! They come with a case and a cleaning cloth! I've worn them 3 times and no longer use them, so I'm selling them! The condition of the product is quite good! In French, "Lunettes" means "glasses," and "Jura" is a place name near the border of France and Switzerland (a center of European eyewear production)!
