Stainless Steel Tea Infuser for Loose Leaf Tea – Extra Fine Mesh Strainer with Heat Proof Double Handles & Lid, Reusable Filter Fits Mugs, Cups & Teapots, Gray

I use an infuser that has a small lid/drip tray and as long as I’m walking normally and don’t overfill my mug I don’t spill it when I’m walking. This isn’t mine but mine is similar in design. https://a.co/d/00YMKMEk
