QSHAVE X6 Blade (6-Blade) Razor Cartridges/Refills with Trimmer Made in Germany Fit QSHAVE Black Series Razor

I have been looking for these for a while. I'm glad i finally found this set of Cartridges. The blades work really well compared to the most expensive ones out there. I am truly impressed since I hadn't really hears of Qshave previously so my doubts are gone. No irritation, as it glides really smoothly, yet effective enough to take out most of the hard to reach beard.Thanks !
