★ This silicone bellows is designed for Single dose. If you pour too many coffee beans at one time (more than 30g), the coffee beans will get slightly stuck in the bellows outlet. The silicone is very elastic. Just press a few more times and the beans will go in smoothly. ★ Mazzer and Anfim grinders have much retention because the outlet channel is too long. The silicone bellows cannot completely blow out the retention in the channel. It must be equipped with a rocket blower to blow out the retention. Please refer to the demonstration video. --> Demonstration video ★ It is not recommended to use this silicone hopper for tilt-type grinders, because the coffee beans are easily stuck in the bellows due to the tilt. For example ◆Monolith Max / Conical / Flat ◆Molar Z ◆Lagom P64....etc. ★ 3D printed products are made of PLA environmentally friendly material, with a heat resistance of 50°C. They can only be washed with cold water. If washing with hot water causes deformation, melting, or collision and breakage due to human factors, the warranty does not apply.
