This is the Comandante Lab Series Hammerhead. It's still rare in Japan, making it quite a collector's item. I purchased it through overseas shopping. I bought it along with another item from the Lab Series, but I've decided to use the other one, so I'm offering the Hammerhead for sale. The burrs are designed to easily grind large beans like Pacamara, bringing out a clear flavor. It's unopened, so you can use it with peace of mind. If you'd like, I can include a genuine glass bean jar (clear or brown) for an additional 2000 yen (without the original box). Both jars would be an additional 3800 yen. I will adjust the price if you contact me through the question function. Please refrain from price negotiations. Thank you.
