# [Peacock pocket warmers](http://www.hakkin.co.jp/)

The original catalytic warmer from Japan. Chances are that you'll need to order from abroad.


## Pros

- Convenient filling funnel. (Honestly this is a huge improvement over Zippo. It's possible to fill this out in the cold without spilling petroleum or freezing your fingers in the process.

Otherwise pretty much identical with the [Zippo](https://outdoors.codidact.com/posts/290872/290873#answer-290873).
