KISS Salon X-Tend Gel Nail Kit

I don't know how to use. I tried 1 pair but it doesn't work. I have to pay alot just to go to the salon. So it'll help if you purchase this! Thank you. This is a KISS Salon X-Tend nail kit for a salon-cured manicure at home. It includes the LED lamp, USB-C cable, and a 5ml tube of gel adhesive.
