Our advantages VS low-priced products :                            Double-layer filter VS Single-layer filter:            1. Filter twice and there is no coffee residue.          2. The dripping speed is reasonable and will not make the coffee weak.
Stainless steel material VS Black plastic material:             304 stainless steel material, can be in contact with boiling water, healthier than plastic material.       Wooden handle VS Cork handle:           1. More insulation.           2. It is easier to clean, while the cork handle is difficult to clean when the coffee drips on it.         3. More durable, while the cork handle is easy to damage and fall off after being wet.
