💎 1. 100% Guaranteed Authenticity Every single piece in our store is thoroughly authenticated and handled with professional care. We source strictly through authorized networks and trusted Japanese certified suppliers. Shop with total confidence and peace of mind.

🌟 2. Carefully Selected & True-to-Life Details We want you to love what you receive. ・All items are photographed in natural lighting to represent colors as accurately as possible (minor color variations may occur depending on screen displays). ・For pre-owned and vintage treasures, any unique characteristics or vintage charm are clearly noted. You are receiving a unique, carefully preserved piece of history!

📏 3. Precision Sizing Measurements are taken flat with meticulous precision (please allow a slight 1-2 cm / 0.5-1 in variation).

⚡ 4. Voltage, Plug & Electrical Specifications Japanese appliances and electronics are renowned worldwide for their exceptional quality and precision engineering. To ensure your device operates safely and lasts for years to come, please carefully review the following specifications: ・Voltage Compatibility: Products are manufactured strictly for Japanese voltage standards (90–110V). Operating the device on a different voltage without proper equipment can cause severe damage or malfunction. ・Plug Type: Our items feature standard Japanese plugs (Type A or B). A plug adapter may be needed to fit your local wall outlet. ・Transformers vs. Conversion Adapters:

- A step-down transformer adjusts the electrical voltage to match the device's requirements.

- A plug adapter only changes the physical prong shape and DOES NOT convert voltage.

- Using a plug adapter alone without a transformer on incompatible local voltage will likely burn out or damage the appliance. ・Liability Disclaimer: Please ensure proper equipment is used. We cannot be held liable for defects, short circuits, or damage resulting from improper voltage use or failure to utilize an appropriate voltage transformer.

📦 5. Safe, Express & Eco-Friendly Packaging Your order will be protected using moisture-resistant, shock-absorbing materials and handled like a gift to yourself. Every shipment includes real-time end-to-end tracking so you can follow its safe journey straight to your door.

✈️ 6. Transparent Customs & Import Duties To ensure a smooth delivery, items are cleared in accordance with international trade standards. Unless pre-collected at checkout by Joom, any local import duties or VAT are handled per your country's customs regulations.

A combination of a ceramic polished core and a stainless steel body: This product features a ceramic polished core that brings out the true flavor of coffee. The body is made of stainless steel, which offers a high-quality feel and excellent durability. It is impact-resistant and safe for outdoor use. This combination makes it suitable for those who want to purely enjoy the original taste of coffee beans and those who want to use it for a long time. The ceramic blade is less prone to flavor conversion due to heat, ensuring a clean taste. A transparent viewing window allows you to check the state of the coffee grounds in real time. Located in the center of the grinding chamber, it allows you to check the amount of coffee grounds, the approximate coarseness, and uniformity in real time while grinding. It also makes it easy to check the remaining amount of beans and convenient for adding more during the process. Detachable Handle and Non-Slip Rubber Grip: The handle is easily detachable. It stays securely in place during use, allowing for powerful grinding. After use, the handle can be removed and inserted into the dedicated rubber non-slip cover on the bottom of the main body for storage. This eliminates the worry of losing the handle and minimizes storage space. Furthermore, this rubber cover also functions as a grip during operation, dramatically improving ease of handling and stability when grinding by hand.
