Greens Steel Coffee Cup Lid - Reusable & Durable Replacement Lid for Travel Mugs - Perfect for Hot/Cold Drinks On-The-Go, Office, Camping & Commuting

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.
