MaterialThe handle and stand are made of raw wood. Ergonomic shape design, comfortable to hold. The needles are made of high-quality stainless steel, anti-rust, anti-corrosion, durable, safe and healthy to use. Affordable PriceWe specially use wood that is lighter than others, so WDT tools work the same but at a more affordable price. (But we have treated the wood with an oil-based coating to make the wood more durable and make the grain and texture of the wood look more pronounced and clear, and it will be a little rough when you look closely.) Fine NeedleThe loopless straight needle and fine needle at the tip perfectly combine rigidity and flexibility, allowing you to break up clumps and extract smoothly. Premium WDT ToolGreat device to break up clumps in the mobile filter and help with leveling. Effectively reduce overflow or channel effect caused by specialty coffee agglomeration during brewing. Achieve greater consistency through extraction when pulling the bar.
