hard to work with [SEP] gel was very hard to work with and the fiberglass sheets were so thick they wouldn t stay in a curve they flattened out while curing the gel also any gel on the nail side of the fiberglass sheet would not cure right i don t know if this was because of the thickness of the sheets or what bought these to mend a small split over the quick on my nail plate instead of using acrylic like i usually do to keep it together until it grew out and it did not work won t be using these again
