This is a collaboration product between Randonnée and Megane no Paris Miki, an outdoor sunglasses. The photochromic lenses are clear in places without light, but change to brown when exposed to sunlight. I purchased these in 2021 and wore them twice for trekking, but I am selling them because I don't wear them often. There are no noticeable scratches or stains, but please understand that these are used items. 【Product Description】 "tekuteku" features a Boston-shaped lens, which is a large, inverted rice ball shape. It can be worn by anyone regardless of gender and also has the function of cutting glare and UV rays. The acetate frame material is non-slip and fits snugly, and the unique luster and color are also attractive. Furthermore, the "crimp-fastened" hinges maintain authentic strength, so you can use them with confidence outdoors. We have designed them with outdoor use in mind, with a durable design, using two crimps to fix both the front and temple sides. In addition, the high nose pads make it easy to fit your face and prevent eyelashes from touching the lenses. The temple tips also have serrations that act as non-slip, and the finish is carefully done down to the smallest details. ・Instant purchase without comment is OK ・No case ・Will be delivered in simple packaging using recycled materials
