thin formula but still my favorite [SEP] definitely my favorite top and base coat it is incredibly solid and durable once fully cured the only issue is the formula is a tad thin and the brushes hold a lot of the polish it takes some practice to not put too much on your nail which affects how long your manicure lasts i still recommend it over any other gel top and base coatalso when i received the package some of the product had spilled out onto the bottles it was not much but it smelled horrible it was almost degrees out when it was delivered and nail polish does not react well with heat so i do not really blame anyone for that i wiped the bottles off with isopropyl alcohol and let them sit for a day or so to let the smell come off good as new
