Greens Steel Coffee Cup Lid - Reusable Replacement Cover for Travel Mugs & Tumblers - Perfect for Hot & Cold Drinks On The Go

I love hooking this onto something or even on my finger (or putting it in pocket.) it keeps things hot or cold for a looooong time. and when I dropped it and popped the handle out the company had a replacement option. very sturdy. I no longer kill the planet with my daily coffee cups.
