I just started doing nails recently it’s been about 2 weeks now and I’m interested on making press on nails to sell at my high school but I’m not sure about the pricing. This is one of the sets I made and was wondering how much would something like this be worth?

I want to make a press on set similar to the one in the photo but was wondering is it okay to use my usual UV gel adhesive to put them on because the end is clear?
