Finum ペーパーティーフィルター

I keep these in my desk drawer at work and they've completely replaced my old infuser ball. Just fill one with loose leaf, drop it in my mug, and toss it after — no soggy cleanup. The paper is thin enough that my tea steeps fully without any grit sneaking through.

Threw a couple in my truck's glovebox and they've saved me on slow afternoons — just fill with loose leaf, brew right in the mug, and toss it after. The paper doesn't tear or leave bits floating in my cup, which is what ruined the last ones I tried.

I’ve started keeping a few of these in my glovebox next to my loose leaf stash, and they’re perfect for a quick cup on the road. The paper feels sturdy enough that I don’t worry about it tearing mid-steep, and cleanup is just a toss into the trash.
