Specially designed for 500g coffee beans, equipped with a 30ml stainless steel coffee spoon, you can control the amount and brewing more precisely, and simply hang it on the jar after use. [One-way valve]CO2 released by coffee and exposure to sunlight will affect the freshness of the coffee, causing the coffee beans to deteriorate and taste.
