Hi, i have these, the pearlised white tips? I really like them but i just keep them for use on myself. I have nearly finished my training at college and have been mostly doing sculptured which i love doing, but find it so hard on myself. I dont know how you would go about a rebalance though with these if using on a client. But for using on myself i love them. I am lucky and have long natural nail beds so the deep smile line is great for me but for someone with a tiny nail bed i think the corners would come quite far down.
Hope that helps, hopefully someone else will give you some more advice about the pro impressions ones!
