No trouble at all! I want your nails to FIT YOU LIKE A QUEEN! So, once you have discovered your sizes, please select "custom" in the size drop down arrow. Then, BE SURE TO LIST YOUR SIZES (thumb to pinky, left to right) in the "note to seller" portion before check out. Handmade sets are made to order, and it is not recommend you file to change the shape, sizing varies by small increments, so you should be able to find your perfect fit.
