Sharp-corner Square
Totally trendy now. Trends change, but these nails always looks good. This shape looks great with short nails and longer ones too.
Long & Oval
These nails look glamorous, but break easily and make typing more difficult.
Rounded & Short
Good for the active gal who hates to fuss. A low-maintenance manicure.
