Fellow Espresso Knock Box Designed to match the color and form factor of the Fellow Espresso Series 1 espresso machine, the Fellow Espresso Knock Box is a compact countertop solution to disposing spent pucks of espresso. Made from a mix of silicone and plastic, the box is designed with a weighted base with a non-slip grip to prevent it from sliding when knocking out pucks. The knock box features an offset placement, allowing pucks to easily fall forward into the center of the box. Hand Wash Only, Not Dishwasher Safe Dimensions: 7 Espresso Pucks (approximately)
