This is the strap for a Thermos children's water bottle cover. It's a genuine product. The plastic parts have some scratches and dirt from my child's use, but it still seems usable. I'm offering it to someone who needs it. My child put it in their backpack for the commute to school and kept it on top of their locker in the classroom. Hanging it around their neck was prohibited except for field trips, so I think it's relatively clean, but please refrain from purchasing if you are concerned about minor details.
