矽膠橡膠球蒸氣塞

I was skeptical a little rubber ball could handle boiling water, but the way it vents steam while keeping the kettle's stem cool is genuinely clever. It's made the whole pot safer to grab, and it hasn't warped or melted after weeks of daily use.

This little ball changed my tea routine completely. I can actually grab the kettle by its stem right after boiling since the steam vents through the top, and it stays perfectly cool.

I was skeptical a tiny silicone ball could keep the kettle stem cool, but my hand stays comfortable even through a rolling boil. Steam still escapes freely, so nothing’s slowed down. It’s become a permanent fixture on my stove.
