This is the genuine Blowup Hopper (250g size) that was used with the Eureka Mignon Specialita. This model is not sold in Japan. It has a 250g hopper capacity and a simple bellows design. Reference Price: The new price is approximately 100 euros + import consumption tax, about 20,000 yen (see photo 6). Features: The bellows-type "blow-up function" inside prevents coffee grounds from stagnating, significantly improving the retention (residue) of ground coffee. I found it very useful because I could always brew fresh coffee. Condition: Used for about 2 years and about 50 times after being installed on the Specialita. It has been cleaned before listing, but there may be fine powder residue due to the nature of the product. Those who are looking for a condition like new should avoid this. However, I have listed it at a significantly lower price, so it is recommended for those who are considering upgrading their Mignon series. Additional Information: There is no usage record other than with the Specialita. According to the manufacturer, it can be installed on other Mignon series grinders because they have the same opening, but if you are considering installing it on something other than the Specialita, please check the diameter of the hopper mounting opening in advance. Installation Tips: It is quite tight for the diameter of the hopper mounting opening on the main unit, so please be careful when installing it. Official Manufacturer Comment: The Eureka Mignon Blowup Hopper is a unique accessory designed to improve weighing accuracy. With a capacity of 250g, the blow-up mechanism expels the powder remaining in the inlet, enabling fresh and accurate weighing. It is easy to install and remove, and can handle both small and large amounts. The transparent design allows you to see the remaining amount of beans at a glance, making it ideal for coffee lovers who value the accuracy and consistency of the extraction process. #coffee #handdrip #frenchpress #espresso #comandante #COMANDANTE #grinder #electricmill #1Zpresso #TIMEMORE #timemore #kalita #hario
