Made of stainless steel material, high quality
Three parts: filter, screw-on damper and lid
The top diameter of the coffee filter is about 6.4cm
Operation:
Simply place the filter on the top of a cup.
Add 2-3 teaspoons of coffee to the filter, then screw on the damper so it is snug (not tight).
Shake the filter a bit to settle the coffee.
Fill up the cup about 1/3 with hot water then wait 20 seconds.
Unscrew the damper 2 turns and fill the cup entirely with hot water.
Place the lid on and wait a few minutes until the water has dripped though.
Add a spoonful (or more) of sweetened condensed milk to the cup before or after you start the process.
The final result is fabulous.
