1. The filter cup is made of high borosilicate glass and has a silicone base, ensuring safety and health. The filter cup is tightly connected to the base and is not easy to slip off.
2. The base is equipped with an on/off valve, which is easy to operate. The valve closes upwards and opens downwards.
3. The soul of the adjustable drip filter cup lies in the base, which is equipped with a steel ball and a switch valve. The steel ball at the bottom effectively blocks the water flow, allowing coffee to be fully soaked and extracted.
4. Easy to control the soaking time of coffee, press the switch to release the valve and filter the coffee, making it easy to master different flavors of coffee.
NOTE:
1. The steel balls in the filter cup are easily lost, so be careful when using them.
When the switch is closed, droplets are normal.

Beautiful and very practical.
It arrived in good time and in good shape. I was afraid the glass pot might break in shipping but, it was well packed. Looking forward to using it.
does everything I wanted to and looks great. I've used better versions of this. by the fact that all of it is frosted glass is quite nice. I kind of had expected it to just come as plastic, but I am very pleasantly surprised. I also enjoy that I can just take out the little ball mechanism they use to plug the hole and use it as a regular v60 cone... if I had a gooseneck kettle for pouring
