Really excellent kit for microblading, comes with an outstanding hard-shell case. This kit is very nice, indeed, and if you're seeking a microblading pen, I suggest you check this one out. The pen itself is beautifully made with a satin silver finish. It looks as though the pen was glass-beaded. Very attractive, very elegant. The kit contains the charging cord, an AC power adapter and 9 needle cartridges (2 types). The charging cord is USB on one end, and USB-C on the other. This allows you to charge from a computer's USB port if you so choose, or anything else that has a USB port. The AC adapter has a USB port, as well. The thing I really love about the pen is the precise calibrations (see photo #6), and the digital LED readout. Unfortunately there is no indicator of battery charge level on the LED readout, but it is very clear and easy to see when working. The pen also works off a single button, which is nice and makes operation simple. One button to turn on/off, and the same button to choose the voltage level. The pen runs smoothly and quietly. Very attractive kit with quality components. Given the quality here I consider this kit a good value.
