They were made of high quality leather and they got more beautiful with saddle soap and age. I use a white noise app on my phone when I sleep and have it on the ocean/campfire setting and it sounds wonderful. Its too inaccurate. I read the sizing chart but that wasnt any help as all it offered was: US Size, UK Size, EU Size, Japan BUT NO ACTUAL FOOT MEASUREMENTS unless there was somewhere else I was meant to look. I would keep and use these lights. This has been a perfect solution for me. One thing I should note though I had to purchase a 3/8 drill bit for the anchors (7$ at home depot). Very pretty especially with skinny jeans. Gucci. I like the LEDS and that you can change the colors - that really helps organize and memorize the controls.
