About This Built to Last☕ With the good properties of high temperature, wear, and corrosion resistance, the engineering plastic processed by stretch molding makes this product durable, resistant to drops, and not easy to crack. Large Capacity☕ The 8.46*8.85*33.66 inches size of this product gives it a large capacity, which makes it suitable for cafes, restaurants, and tea shops in a high-traffic area and allows for infrequent cleaning of coffee grounds, saving you time. Thoughtful Design☕ The rubber knocking bar can reduce noise and vibration when knocking coffee grounds while protecting the coffee machine handle. The deep bowl design can prevent coffee grounds from splashing all around. Environmental-friendly☕ As coffee grounds contain abundant trace elements and are very suitable for the growth of flowers and plants, they can be used for flower cultivation to prevent pests and promote the flowering of seedlings and flowers. Simple & Minimalist☕ The commercial knock box simple black color can match most shop or home decoration styles, which is practical and unobtrusive.
