Did exactly as the instructions told me on the box. Advised not to get wet for 2 hours, which I followed - they came off later in the day. All 10 fingers. Annoyed because I spent £45 on the starter kit and now I feel like I’ve just wasted my money. I was really looking forward to be able to do my nails at home, because I thought this might be a cheaper alternative than getting my nails done in the salon.
