The base is made in Adelaide, Australia from high-grade stainless steel, engineered for durability and strength. For Pullman's Barista Tamper devotees, the BigStep retains the feel of a regular Barista base with an adjustable height handle suitable for all palm sizes and grips.  With the soft compression zone to cushion the force of your tamp and protect your fingers, you'll appreciate the luxury. The Pullman BigStep is designed for those who tamp with a perfect vertical action as the big base has little room in the basket for errors in technique.  Correct use also means your coffee bed will be tamped evenly and fully. The design can be used with all variations of dose weights (low dose / high yield or high dose / low yield) producing incredible extraction and mouthfeel, getting the most out of your coffee beans. The BigStep tamper is suited for baskets sized 58.7mm or greater.  Professional espresso baskets such as VST baskets or Pullman Filtration Baskets have a consistent internal diameter and ensure a perfect with the BigStep tamper.  Results may vary if different baskets are used. https://www.youtube.com/watch?v=6AySmMFmJIE https://www.youtube.com/watch?v=hhpmLz3L-fM
