I purchased these from an overseas website last year for use with my 9barista and have been using them personally. They are easy to use, with a good weight and comfortable grip. This is a set of a distribution tool and a tamper. • 53.3mm • True Black Walnut Purchase price: Tamper: 28,800 yen Distribution tool: 28,800 yen Buying both new is quite expensive, so how about taking this opportunity? *These are used items. Please refrain from purchasing if you are looking for a perfect product.
